Any heart murmur we hear can become a key to detecting serious health problems.

The identification and analysis of heart murmurs can reveal valvular dysfunction, congenital or acquired heart defects, structural abnormalities, and more. These issues are often caught at early stages, when treatment is most effective and patient outcomes can be significantly improved.

👂Every murmur has its own signature: timbre, frequency, intensity, point of maximal intensity (PMI), and timing within the cardiac cycle (systolic or diastolic).�With AI-enhanced phonoscopy using Stethophone, clinicians can analyze these features quickly and accurately. One murmur may suggest valve stenosis, another may indicate valve regurgitation, each linked to a specific valve or structure.

📝 Tracking Changes Over Time�
For patients with known heart conditions, regular auscultation helps monitor progress. It shows whether a condition is stabilizing, improving, or worsening and helps assess the response to treatment.

🫀 A Tool in the Doctor’s Hands�
Even though modern medicine offers highly accurate tools such as MRI, CT, and echocardiography, phonoscopy remains one of the earliest and most accessible diagnostic methods. It serves as a fast-screening tool that guides whether more advanced testing is needed. The physician’s ability to interpret cardiac sounds correctly is a skill that can truly save lives.

When evaluating a heart murmur, clinicians systematically assess several characteristics to help determine its cause and significance. Heart sound analysis isn’t just about noticing a sound, it’s about characterizing every detail.

Know the 6 essential characteristics you MUST evaluate for every heart murmur.

📝 A frequent finding in children, but sometimes this kind of murmur can be present in adults.
☝Valvular aortic stenosis can be erroneously classified as a Still’s murmur.
🧐Aortic stenosis murmurs have a longer duration and contain higher frequency vibrations.

🎧 The Levine Scale is a classic system for grading the intensity of heart murmurs, ranging from 1/6 to 6/6.
Developed by cardiologist Samuel Levine in 1933, it remains the gold standard in international cardiology practice.

Knowing and using this scale:
- Simplifies communication with international colleagues
- Is essential for certification and standardized reporting
- Is referenced in all major global guidelines
It’s a simple yet powerful tool that helps standardize auscultation, support diagnostic reasoning, and improve communication among clinicians — a fundamental skill every practitioner should master.

📝How to Document Findings
✅ Correct: “Systolic murmur 4/6 at the aortic area, radiating to the carotids, with palpable thrill.”
❌ Incorrect: “Loud heart murmur.”

⚠️ Important Nuances
Intensity ≠ Severity
A soft diastolic murmur (2/6) may signal severe aortic regurgitation.
A loud systolic murmur (4/6) can be innocent in a child.

Always assess:
✅ Timing: systolic or diastolic
✅ Location & radiation
✅ Character: harsh, musical, blowing, decrescendo, etc.
✅ Associated symptoms: dyspnea, chest pain, syncope, edema

Takeaway:
The Levine Scale remains a timeless clinical language — a simple, universal code that bridges generations and borders in cardiology.

Had an inspiring experience at the Scientific Sessions 2025 in New Orleans.

It was a privilege to engage with innovators and thought leaders shaping the future of cardiovascular care at the Health Innovation Pavilion.

A huge thank-you to the American Heart Association for organizing such a meaningful event, and to the Health Innovation Pavilion team for creating a space where science, technology, and care truly come together.

Special thanks to Mark Attila Opauszky, CEO of Sparrow BioAcoustics, for sharing valuable insights on device-agnostic AI and demonstrating Stethophone.

Appreciative of every conversation, new connection, and shared heartbeat that made this event truly memorable.

The era when ANOCA (Angina with Non-Obstructive Coronary Arteries), INOCA (Ischemia with Non-Obstructive Coronary Arteries), and MINOCA (Myocardial Infarction with Non-Obstructive Coronary Arteries) were considered mere “diagnoses of exclusion” is over.

Contemporary cardiology now recognizes them as distinct clinical entities, each with specific pathophysiological mechanisms, microvascular dysfunction, vasospasm, or plaque disruption, requiring targeted evaluation and management.
The key is not a generic approach, but a mechanism-driven workup using functional coronary testing or advanced imaging to clarify the underlying cause and guide tailored therapy.

Cardiovascular Research Foundation TCT 2025 finished two weeks ago, and this year, there was a noticeable shift in emphasis toward the detection of structural heart disease. Whereas historically the conversation has centered on speed to intervention, it is now increasingly about finding disease earlier in the population.

Among the more impactful presentations, the PREVUE-VALVE study, led by Dr. David Cohen with Dr. Michael Brener as first author and conducted under the Cardiovascular Research Foundation, presented a refreshed look at the prevalence of valvular heart disease (VHD) in older adults. The results were striking.

Don’t Overlook Heart Murmurs and Their Clinical Significance!
Here’s the essential information you need to know. 🫀
📝Classification

By Timing
• Systolic (between S1–S2): Most common; may be innocent or pathological
• Diastolic (between S2–next S1): Always pathological
• Continuous: Persists throughout the cardiac cycle (e.g., patent ductus arteriosus)

By Intensity (Levine Scale)
• Grade 1/6 – Barely audible
• Grade 2/6 – Quiet but clearly heard
• Grade 3/6 – Moderately loud
• Grade 4/6 – Loud with palpable thrill
• Grade 5/6 – Very loud, audible with minimal contact
• Grade 6/6 – Audible without direct contact

📝Clinical Significance
Functional (Innocent) Murmurs
• No evidence of structural heart disease
• Common in children and young adults (seen in up to 50%)
• Typically soft, systolic, and asymptomatic
• May vary with body position or respiration

Pathological Murmurs — Key Red Flags
⚠️ All diastolic murmurs are pathological
⚠️ Grade ≥3/6 intensity
⚠️ Associated symptoms: dyspnea, syncope, or chest pain
⚠️ Abnormal S2 (e.g., wide or fixed splitting)
⚠️ Harsh quality or radiation

Common Pathological Etiologies

Valvular Disease
• Aortic stenosis (systolic ejection murmur)
• Mitral regurgitation (holosystolic pattern)
• Aortic regurgitation (early diastolic murmur)
• Mitral stenosis (mid-diastolic rumble)
Structural or Functional Abnormalities
• Ventricular septal defect
• Atrial septal defect
• Hypertrophic cardiomyopathy

When to Refer
✅ Any diastolic murmur
✅ Systolic murmur with clinical symptoms
✅ Grade ≥3/6 systolic murmur
✅ Change in a previously documented murmur
✅ New murmur in an adult >40 years

Key Takeaway?
Early recognition through AI Phonoscopy and bioacoustic signal analysis supports the detection of significant valvular and structural abnormalities before irreversible cardiac remodeling occurs.

🫀 Understanding Heart Failure Severity: NYHA Functional Classification
The New York Heart Association (NYHA) Functional Classification is the gold standard system in cardiology for assessing the severity of heart failure. It categorizes patients into four functional classes based on how symptoms limit physical activity. Knowing these is essential for diagnosis, treatment, and predicting outcomes! 👇

Class I: ✅ No Limitation. Ordinary physical activity does not cause fatigue, palpitations, or shortness of breath (dyspnea).

Class II: ⚠️ Slight Limitation. Comfortable at rest, but ordinary activity results in symptoms.

Class III: 🛑 Marked Limitation. Comfortable at rest, but less than ordinary activity causes symptoms.

Class IV: 🚨 Unable to Perform. Symptoms of heart failure are present even at rest; any activity causes discomfort.

This simple, standardized framework guides critical treatment decisions and enables consistent communication among healthcare professionals worldwide. It's truly foundational in clinical practice and research.

Save this essential reference for a quick clinical review and Share to promote awareness of this widely recognized standard in heart failure assessment! 💙
