Heart Care Services in Miami, FL
This page is educational and does not provide medical advice, diagnosis, or treatment. Individual results vary. Please consult a licensed physician for guidance about your specific situation.
We diagnose and treat the full spectrum of cardiovascular conditions, including coronary artery disease, heart failure, valve disease, structural heart disease, arrhythmias such as atrial fibrillation, and peripheral vascular disease. Every patient receives a personalized care plan built around their specific symptoms, lifestyle, and long-term goals.

Symptoms That Should Prompt a Cardiology Evaluation
The following symptoms are not always caused by heart or vascular disease, but they warrant an evaluation with a board-certified cardiologist — especially if they are new, worsening, or interfering with daily life:
- Chest pain, tightness, or pressure — especially with exertion
- Shortness of breath at rest or with light activity
- Palpitations, skipped beats, or a racing heartbeat
- Fainting, near-fainting, or unexplained dizziness
- Leg cramping when walking that resolves with rest
- Swelling in the ankles, feet, or legs
- Unusual fatigue, especially with a known cardiac risk factor
- Family history of early heart disease or sudden cardiac death
Why It Matters
Heart and vascular disease often progresses silently for years before symptoms appear. Early diagnosis of coronary artery disease, arrhythmias, valve disease, or peripheral artery disease can meaningfully lower the risk of heart attack, stroke, heart failure, and limb complications — and, in most cases, allows treatment with medications or minimally invasive, catheter-based procedures instead of open surgery.
How We Evaluate Your Heart
Every evaluation starts with a careful history and physical exam. Depending on your symptoms and risk factors, your cardiologist may recommend:
- Electrocardiogram (ECG) and rhythm monitoring
- Echocardiogram (heart ultrasound)
- Stress testing (exercise or pharmacologic)
- Advanced lipid, inflammatory, and metabolic labs
- Coronary calcium scoring or CT angiography
- Peripheral vascular ultrasound where indicated
- Cardiac catheterization when a definitive answer is needed
