Heart Treatment Without Angioplasty / Bypass surgery - dr dk gupta To know more..like this page...and learn more about the treatment.

As per american guidelines, medical treatment alone is very much possible for heart vessel blockage or blockage in heart without need for angioplasty/bypass surgery. Many clinical studies have proved that angioplasty/bypass surgery gives no benefit compared to medical treatment in many patients of blockage in heart & its results are almost equal to that of medical treatment or sometimes even infer

ior to that of medical treatment. This is the only reason american heart association & american college of cardiology have made some guidelines in favour of medical treatment which every doctor should follow.Due to these guidelines only recently in america angioplasty/bypass surgery have been reduced to the tune of 40% which is a remarkable figure.

!! Just a single high-fat meal can lead to heart disease !!

Investigation, finds dramatic and almost immediate changes in the blood vessels of healthy men after they have consumed a single high-fat meal.
fast food
A single meal high in fat — such as those typical of fast food — may immediately wreak havoc on your arteries, shows a new study.
It is well known that a diet high in saturated fat is a contributing factor to the risk of heart disease.

The Centers for Disease Control and Prevention (CDC) warn that a diet high in fat and cholesterol may raise the risk of heart disease and cardiovascular illnesses, such as atherosclerosis — a disorder in which arteries can lose their elasticity.

Most of us understand that such a diet predisposes consumers to heart disease over time, but could it be the case that the effects of a single high-fat diet are immediately noticeable and damaging?

New research — carried out by scientists at the Medical College of Georgia (MCG) in Augusta — suggests that they are.

Tyler W. Benson, a doctoral student in The Graduate School at Augusta University, is the study's first author.

Studying high-fat meals and red blood cells
Benson and colleagues divided 10 healthy men — who had been exercising regularly and had healthy levels of cholesterol and lipids in their blood — into two groups.

One group of five men was fed a super-high-fat milkshake. The fat in each meal was individually calculated so that participants were given levels of fat that were proportionate to their body weight.

By contrast, the other five men were fed a meal with the same number of calories, but low in fat.

The researchers took biochemical tests of the participants 4 hours after the meals, focusing on the impact of high-fat food on red blood cells — the cells that carry oxygen through our blood.

As the researchers explain, we have about 25 trillion red blood cells that affect all the other cells in the human body.

Part of the reason why they are so important to cardiovascular health is that they carry cholesterol through the cardiovascular system, as well as nitric oxide. These are two substances that influence the elasticity of blood vessels.

High-fat meals and red blood cell 'spikes'
The researchers found several changes to the red blood cells of the study participants. "They changed size, they changed shape, they got smaller," says Dr. Ryan A. Harris, clinical exercise and vascular physiologist at Augusta University's Georgia Prevention Institute.

Dr. Julia E. Brittain, vascular biologist at the MCG Vascular Biology Center and one of the corresponding authors of the study, explains these changes further, saying, "[Y]our red blood cells are normally nice and smooth and beautiful and the cells, after consumption of a high-fat meal, get these spikes on them."

These spikes on red blood cells, the author says, makes them particularly damaging to blood vessels and sets the ground for heart disease.

Additionally, the researchers found an increase in reactive oxygen species, a change that can lead to disruptions in how the red cells function.

Furthermore, the researchers found another significant change: an increase in an enzyme that is believed to be implicated in atherosclerosis and heart attack.

The enzyme is called myeloperoxidase (MPO) and previous studies have linked it to a loss of elasticity in the blood vessels, as well as to the oxidation of high-density lipoprotein cholesterol, or the so-called good cholesterol.

Referring to the raised levels of MPO, corresponding author Dr. Neal L. Weintraub, who is also an associate director of MCG's Vascular Biology Center, says, "This is a really powerful finding."

Damaging effects are reversible
Finally, the authors also noticed changes in white blood cells, with the high-fat diet raising levels of pro-inflammatory monocytes, the same way that an infection would.

Although these these harmful changes to the blood vessels were seen 4 hours after the meal, the researchers note, the damage is reversible and the changes tend to go away after 8 hours.

However, the harms are likely to last if one high-fat meal is followed by another, the researchers caution.

"We see this [study] hopefully as a public service to get people to think twice about eating this way."

Dr. Neal L. Weintraub
"The take-home message is that your body can usually handle this if you don't do it again at the next meal and the next and the next," adds Dr. Brittain.

...!!!!In three vessel blockage of >90%............ if ischemia (deficient blood supply in heart muscle)

22/03/2026

❤❤❤❤
❤MUST CIRCULATE❤
Recently, one person was admitted to a superspeciality hospital at Delhi , due to severe chest pain. The doctors suggested Angiography.
Upon undergoing Angiography at multi speciality Hospital Doctors diagnosed multiple blockages of more than 90% for which angioplasty ruled out and instead, suggested 'Bypass Surgery'.
Meanwhile, after discussing the matter with relatives and close friends, fresh information came from a family friend.
A test known as stress MPI which is AHA (american heart association ) approved and done in many countries, by this test it is proved that actual supply reaching to the heart muscles is still more than 70%, despite 90% blockage in all three vessels due to mutiple collaterals or natural bypass developed automatically, therefore no need of angioplasty or bypass surgery as per american heart association guidelines.
Instead in these patients meticulous treatment with medicines only as per AHA guidelines is given & patient improves within few days with nearly no risk of reheart attack or readmission in hospital
Currently, this management is being done under guidance of few doctors only.
There are many patients who had to undergo by-pass surgery from major hospitals; but, instead after undergoing the new management, they are absolutely fine and are leading a normal life.

Heart Attack in Patients with Normal Angiography Has A Prevalence of 8-25% - An OCT Study of 1178 Patients

Acute coronary syndrome (ACS) in patients with normal coronary arteries has a prevalence of between 8% and 25%.1, 2 Several mechanisms have been implicated in its etiopathogenesis, including coronary vasospasm, hypercoagulable states, and embolization.2 Coronary angiography can assess the extent of stenosis but not the state of atheromatous plaques. The technique is therefore of limited use when complicated plaques are present, particularly in the absence of significant lesions.3 Atherosclerotic plaques can, however, be characterized by optical coherence tomography (OCT).2, 3 Previous studies with this technique in ACS have focused on characterizing the substrates of angiographically significant lesions.4, 5 None, however, have studied unstable substrates in patients with insignificant findings on angiography. In a recent study of patients who were resuscitated after sudden death and had lesion-free coronary arteries, intracoronary ultrasound allowed identification of unstable plaque substrates in all patients.6 OCT has demonstrated better resolution than intracoronary ultrasound in the characterization of atheromatous plaques.4, 5 The objective of our study was to identify the presence of unstable substrates using OCT in patients with ACS and angiographically normal coronary arteries or angiographically insignificant lesions (< 50%).
Between April 2012 and September 2014, 1178 patients with high-risk ACS underwent coronary angiography. Of these, 53 (5.14%) had normal coronary arteries and 58 (5.63%) had angiographically insignificant lesions. Of these 111 patients, 21 met the following criteria: a)clinical manifestations of angina or equivalent; b) electrocardiographic findings indicative of ischemia; c) elevated levels of biomarkers of myocardial damage (troponin I or ultrasensitive troponin I), and d) wall motion abnormalities on echocardiography, magnetic resonance imaging, or ventriculography. Based on angiographic irregularities and electrocardiographic and wall motion abnormalities, the artery considered the cause of ACS was selected and OCT (Dragonfly™ Duo OCT Imaging Catheter, St Jude Medical; St. Paul, Minnesota, United States) performed. Patients with ST-segment elevation ACS underwent emergency catheterization. None received fibrinolytic agents. In patients with non-ST-segment elevation ACS, an early invasive strategy was followed with coronary angiography in the first 24 to 48 hours. Only 1 patient had a Q-wave infarction and all had elevated troponin I or ultrasensitive troponin I and creatine kinase.
The baseline characteristics of the patients are summarized in Table. The mean age was 54.7 ± 14.79 years and 7 patients (33.3%) presented with ST-segment elevation ACS. The artery most frequently considered the cause of the event was the left anterior descending artery (66.7%). Quantitative coronary angiography and OCT showed an acceptable correlation (TableTable) showed that 20 patients had signs of arteriosclerosis and 9 had stable plaques (Figure). Of these 9 plaques, 2 were considered vulnerable as they had a very thin fibrous cap with a large necrotic core. In 8 patients, residual thrombotic material was found (Figure), associated with the presence of ruptured plaques. Ten patients had ruptured plaques (Figure), 2 had plaque erosion (Figure), and 3 had superficial calcified nodules with thrombus (Figure) or rupture of a thin fibrous cap. Eleven patients had several remarkable findings, 6 had only stable plaques, and 1 had normal coronary arteries with no findings on OCT; 5 patients (22.7%) had anterior ST-segment elevation ACS and apical akinesis with subsequent normalization of ventricular function, indicative of tako-tsubo syndrome. Only 1 patient had a normal left anterior descending artery on OCT and 4 had unstable substrates. In summary, of the 21 patients studied, 20 showed signs of coronary arteriosclerosis and 14 (66.7%) had signs of complicated atherosclerotic plaque that could cause ACS, despite the absence of angiographically significant lesions on coronary angiography.

Chinese exercise is good for the heart

One of the best-known chinese exercise,Tai Chi, is recommended by Harvard Medical Center's Women's Health Watch for anyone, of any age, including those in a wheelchair. Benefits include helping people to maintain strength, flexibility and balance.
Stemming from ancient Chinese martial arts, Tai Chi combines gentle physical activity with elements of meditation, body awareness, imagery and attention to breathing.
"Qi," pronounced "chi," refers to an energy force that, according to Chinese philosophy, flows through the body. Tai Chi and Qigong aim to unblock and encourage the flow of qi.
Participation in Chinese exercises decreased the average systolic blood pressure level by more than 9.12 mmHg and the diastolic blood pressure by over 5 mmHg. Small but statistically significant reductions occurred in low-density lipoprotein (LDL), also known as "bad cholesterol" and in triglycerides.

Angioplasty gives no benefit in stable patients of Heart Attack After 24 Hours

Revisions To Guidelines For Angioplasty Use Have Not Translated Into Effective Clinical Practice For Heart Attack Patients

Although guidelines are avaiable for the appropriate use of percutaneous coronary intervention (PCI) in patients with a blocked coronary artery post myocardial infarction (heart attack), their adoption in clinical practice is still questionable. This was revealed in a report published recently in one of the Less is More series of the Archives of Internal Medicine, one of the JAMA/Archives journals. The background information in the article has mention of a study entitled 'Occluded Artery Trial' (OAT) which was sponsored by the National Heart, Lung, and Blood Institute and was published in 2006. In this study, completely blocked coronary arteries that were identified in stable patients after a minimum of 24 hours post myocardial infarction (MI) (on calendar days 3 to 28), were examined for the effects of PCI, such as the use of balloon angioplasty and stenting. The authors state:"The OAT results provided objective evidence that the use of PCI did not lead to a reduction in clinical events and that the beneficial effect on angina and quality of life was small and not durable. Percutaneous coronary intervention was more costly than optimal medical therapy alone; hence, these findings should have discouraged routine PCI in this setting."The American College of Cardiology and the American Heart Association updated their guidelines after the results of this study were made available to the public. Researcher Marc W. Deyell, (M.D) from the University of British Columbia in Vancouver, Canada and his team studied whether any changes to clinical practice had taken place after the revision of guidelines. Data between 2005 and 2008 were collected by the researchers from the CathPCI Registry. The CathPCI Registry is a database with information from all U.S. hospitals that perform cardiac catheterization. A comparison of PCI rates, before and after the OAT results were published and guidelines updated, was made, and the trends in hospitals in the highest quartile for reporting diagnostic procedures were studied. A cohort of 28,780 patient visits from 896 hospitals was included in the current study. Before the OAT results were published 11,083 percutaneous coronary interventions were performed; while 7,838 were performed between publication and guideline changes; and another 9,859 after the revised guidelines were in place. After adjusting for other variables, researchers did not report any significant decrease in the monthly rate of PCI performed for occlusion, both after the OAT results were published and after the guidelines were updated. PCI rates did not decline after OAT publication even in hospitals that were regularly reporting procedures done for diagnostic purposes to the CathPCI registry; however in these hospitals a small gradual decline was observed after the guidelines were updated. The authors stated:"In conclusion, among this large cross-section of hospitals in the United States we found only modest evidence that the results of the OAT and its incorporation into major guideline revisions have influenced cardiology and interventional cardiology practice over the subsequent 1 to 2 years." "Percutaneous coronary intervention of total occlusions identified greater than 24 hours after MI remains commonplace despite little evidence to support its use in stable patients and new clinical practice guidelines recommending against it."The researchers highlighted that many patients may be receiving an expensive intervention that may not be of any use to them and that the huge amount of time and effort devoted to the research did not translate into effective clinical practice for such patients in the U.S.

Genes Play Largest Role In Heart Blockage Not Family Lifestyle

It has long been known that hereditary factors play a role in coronary heart disease. However, it has been unclear whether the increased risk is transferred through the genes or through an unhealthy lifestyle in the family. A new study from the Center for Primary Health Care Research in Sweden, published in theAmerican Heart Journal, shows that genes appear to be most important. The researchers, led by Professor Kristina Sundquist, studied people who had been adopted and compared them with both their biological and their adoptive parents. The Swedish multi-generation register and the in-patient care register were used to follow 80 214 adopted men and women. They were all born in 1932 or later and developed coronary heart disease between 1973 and 2008. Using the registers, the researchers also studied the adoptive parents and biological parents over the same period. The risk of coronary heart disease in adopted individuals who had at least one biological parent with coronary heart disease was 40 - 60% higher than that of a control group. There was no increased risk in individuals whose adoptive parents suffered from coronary heart disease, not even if both adoptive parents had the disease. "The results of our studies suggest that the risk of coronary heart disease is not transferred via an unhealthy lifestyle in the family, but rather via the genes," says Kristina Sundquist, a professor at the Center for Primary Health Care Research in Malmö, Sweden. "But that does not mean that one's lifestyle is not a factor in one's own risk of developing coronary heart

AHA updated scientific statement on measurement of BP

Good technique with validated, automated blood pressure machine use is key to accuracy, according to an updated scientific statement on BP measurement from the American Heart Association (AHA).

To ensure accurate measurement of BP, the AHA has issued recommendations on training in auscultatory BP measurement, assessment of knowledge of the doctor, skills of the technician or provider, among others.

Among the key recommendations are:

The observer must be able to see the manometer dial at eye level without straining and read the sphygmomanometer no further than 3 ft away.
The observer must be able to hear the Korotkoff sounds and be able to conduct the cuff deflation, listen to Korotkoff sounds and read the sphygmomanometer simultaneously.
Only well maintained validated devices must be used.
Observers should also know how to interpret and how and when to communicate BP readings to healthcare providers and patients.
Retraining of healthcare professionals should be considered every 6 months to 1 year.
The appropriate cuff size should be selected.
o Arm circumference should be measured at the midpoint of the acromion and olecranon.

o BP cuff bladder length should be 75-100% of the measured arm circumference.

o BP cuff bladder width should be at 37-50% of the patient’s arm circumference.

o Avoid rolling up the shirtsleeves as a tourniquet effect may result.

The observer must understand variability of BP by time of day, exercise, and timing of antihypertensive medication consumption
o Systolic BP is 3–10 mmHg higher in the supine than the seated position.

o Diastolic BP is ≈1–5 mmHg higher when measured supine vs seated

o Crossing legs during BP measurement may raise SBP by 5–8 mmHg and DBP by 3–5 mmHg.

o If a patient’s back is not supported (e.g., the patient is seated on an examination table), SBP and DBP may be increased by 5-15 and 6 mmHg, respectively

AHA has also described following six steps for proper seated office BP measurement:

Properly prepare the patient
Use proper technique for BP measurements
Take the proper measurements needed for diagnosis and treatment of elevated BP/hypertension
Properly document accurate BP readings
Average the readings
Provide BP readings to patient

!! Silent Bradyarrhythmia Needs No Treatment & No Pacemaker Is Needed !!
- Study Published in JAMA Cardiology 15th Feb 2023

Bradycardia is a lot more common than generally believed, but is often asymptomatic and not clinically relevant, and may lead to needless pacemaker therapy, suggests a post-hoc analysis of a major study.

The arrhythmia's presence overall in the randomized LOOP trial predicted an excess risk of syncope and death, and it didn't matter how it was detected. Bradyarrhythmia revealed incidentally at long-term cardiac rhythm monitoring was no more predictive than when it was picked up in a usual-care setting.
Still, people in the trial with implantable loop recorders (ILR) had six times the chance of being diagnosed with bradyarrhythmias than those in the usual-care control group. LOOP entered older persons in the community without known arrhythmias but with risk factors like diabetes or hypertension.
About 80% of such arrhythmias at ILR monitoring were asymptomatic, compared to less than one fourth in the usual-care group. Yet pacemaker implantation for bradyarrhythmia was 53% more likely in the ILR group, according to a report published February 15 in JAMA Cardiology.
Most participants with asymptomatic bradycardia did not receive treatment for it, yet the study — despite the mostly conservative management — still showed "overtreatment with pacemakers" in the ILR group, observed lead author Søren Zöga Diederichsen, MD, PhD, Copenhagen University Hospital–Rigshospitalet, Copenhagen, Denmark.

Bradyarrhythmia overall predicted later syncope and all-cause and cardiovascular (CV) death, but did so regardless of whether the patient was ILR-monitored or received a pacemaker.
"We didn't see any signal, not even a small signal, toward a health benefit from monitoring and detecting bradycardias, or from acting on them conservatively or implanting pacemakers," he noted.
The study "emphasizes that you should have symptoms" to justify pacemaker therapy for bradyarrhythmias, regardless of how they were detected, Diederichsen said.
"Clearly ILRs may identify patients with bradyarrhythmias deserving of treatment" when they are associated with symptoms, an accompanying editorial agrees. In the current analysis, however, "a large proportion of bradycardic events were completely asymptomatic." Yet bradycardia predicted syncope and CV death in both the ILR and usual care groups, it notes.
"This does raise the question as to whether bradyarrhythmia may be a risk marker for underlying nonarrhythmic conditions to which preventive strategies and treatment should be directed," write editorialists Mark H. Schoenfeld, MD, Yale University, New Haven, Connecticut, and Kristen K. Patton, MD, University of Washington, Seattle.
"In an aging population with ever-increasing comorbidities, it may become increasingly important to rule out bradycardia as a manifestation of a more sinister underlying disease," they note, and to identify "patients who may be particularly vulnerable to adverse outcomes of progressive distal conduction disease."
The previously published LOOP trial, conducted at four sites in Denmark, compared ILR screening for AF to usual care in 6004 patients at least 70 years or older, most with hypertension. The main results showed little benefit from screening for AF in prevention of incident stroke or systemic embolism over about 5 years.
The current LOOP analysis, post-hoc with all the associated limitations, followed incident bradyarrhythmia in the ILR and usual-care groups; any treatment of the arrhythmia was at physician discretion. The total cohort averaged 75 years in age and 47.3% were women.

The rate of incident bradyarrhythmia was 8.1% overall; it was 20.8% for those with ILR monitoring and 3.8% in the usual care group, for a hazard ratio (HR) of 6.21 (95% CI, 5.15 - 7.48, P < .001).
The arrhythmia was asymptomatic in 23.8% of usual-care patients and 79.8% of those with an ILR.
Bradyarrhythmia was significantly more likely among older patients, male patients, and those with a history of syncope, the group reported.

Pacemakers were implanted for bradyarrhythmia in 2.9% of usual-care patients and 4.5% of those with ILR monitoring for an HR of 1.53 (95% CI, 1.14 - 2.06, P < .001).
Among usual-care patients, bradyarrhythmia (vs no bradyarrhythmia) was associated with 5.2 times the risk for incident syncope (P < .001). That risk for syncope went up 2.6 times (P = .01) in the ILR group.
The corresponding risks for CV death among controls and among ILR patients increased 4.8 times (P < .001) and by 3.1 (P < .001), respectively. The risks for death from any cause tripled (P < .001) and rose 2.5 times (P < .001) among bradycardic controls and ILR patients, respectively.

Bradyarrhythmia was not significantly related to sudden cardiac death in either group, the report notes.
Given the increasing use of heart rhythm monitoring "inside and outside the clinical setting," it states, "bradyarrhythmias are likely to be detected more often, sometimes as an incidental finding. Knowledge about the underlying prevalence and prognostic significance could help guide decisions."
The study "teaches us a little bit" about the true prevalence of bradyarrhythmias in the general population, including asymptomatic cases that appear to be subclinical or "physiological," Diederichsen said in an interview.

It also suggests that such bradycardia will be increasingly observed as use of ILR for arrhythmia screening expands in practice, he predicted. It may also be picked up more often by wearables and other rhythm-monitoring technology used by the public.
In the latter case especially, Diederichsen said, the current analysis could potentially help alleviate any concerns that bradyarrhythmia without symptoms is something that has to be specifically treated.
