Exercise: The Most Powerful Prescription for Your Heart ❤️

If there were a pill that could lower your blood pressure, improve your cholesterol, reduce stress, strengthen your heart, boost your mood, and help you live longer — everyone would want it.

That “pill” already exists. It’s called exercise.

Regular physical activity is one of the most effective, evidence-based ways to prevent heart disease and improve cardiovascular health. Just 30 minutes a day of moderate activity - like walking, biking, swimming, or even dancing - can make a lasting difference.

You don’t need a gym membership or fancy equipment. The key is consistency. Start small, move daily, and treat exercise like you would any other prescription - something you do for your long-term health.

Your heart doesn’t just need medication - it needs motion. ❤️

We are again doing cutting edge work at Delray!

It's another medical milestone for Delray! ❤🎉👏 Today we completed our first TRICvalve implantation for tricuspid regurgitation - and we are one of only three sites in Florida to do the procedure. Congratulations to Tilak Pasala, MD, Medical Director of Structural Heart and his incredible team of clinicians!

TRICvalve implantation is a transcatheter procedure for treating severe tricuspid regurgitation (TR) by inserting two self-expanding bioprosthetic valves into the superior and inferior vena cava (SVC and IVC). This minimally invasive approach aims to prevent the backward flow of blood, which helps improve quality of life and right heart function without the high risks of open-heart surgery. The implantation can reduce congestion, improve cardiac output, and lead to significant improvements in symptoms and quality of life for high-risk patients.

A Hidden Heart Risk You May Not Have Heard Of: Lipoprotein(a)

Most individuals are familiar with "bad" cholesterol (LDL-c) and "good" cholesterol (HDL-c). However, there exists another crucial particle called Lipoprotein(a), or Lp(a), that many individuals are unaware of, and it may be a missing link in heart disease risk.

Why it matters
• Elevated Lp(a) levels increase the risk of heart attacks, strokes, and aortic valve disease, even if your LDL and HDL are within normal ranges.
• Lp(a) is primarily genetic, meaning lifestyle modifications such as diet and exercise will not lower it.
• If heart disease runs in your family, especially at a young age, testing for Lp(a) can be crucial.

What’s new in research
Currently, several large clinical trials are underway testing new medications that specifically target and lower Lp(a). These drugs have shown promise in early studies and could offer a new way to protect individuals who carry this hidden risk factor.

What you can do today
• Inquire about an Lp(a) test: It’s a simple blood test that can provide valuable insight into your heart risk.
• If you have high Lp(a), your doctor may recommend closer monitoring and more aggressive management of other risk factors (blood pressure, LDL cholesterol, diabetes).
• Stay informed, as treatments are on the horizon, and the next few years could be practice-changing.

Takeaway: Knowing your Lp(a) level is another powerful step toward personalized heart care.

Big news in heart health: the ACC and AHA just released updated guidelines for high blood pressure.

The new recommendations stress earlier treatment, protecting brain health, better kidney testing, and personalized risk tools to guide care. Lifestyle changes remain the foundation, but we now know that early and tailored treatment can make an even bigger difference in protecting your heart and brain.

If you have questions about what this means for you, let’s talk at your next visit.

The New York Times has published a compelling article on amyloidosis, a condition we're now detecting with increasing frequency and at earlier stages, offering new opportunities for intervention and hope.

A quiet revolution in care is helping patients with cardiac amyloidosis, a form of heart failure that long stumped doctors.

Your heart deserves daily care—not just attention during a crisis.
As a cardiologist, I always remind my patients: small changes make a big impact. Just 30 minutes of walking a day, cutting back on processed foods, and managing stress can significantly lower your risk of heart disease.
