  • My husband snores like a rhino on steroids, and sometimes stops breathing at night.

    "This is probably obstructive sleep apnea, which can have negative effects in your cardiovascular system. A sleep study is probably a good idea."

  • I was told I had a heart attack years ago. How low should my cholesterol be?

    "The LDL (“bad”) cholesterol should be under 100 mg/dL for most people. But under 70 mg/dL (and perhaps under 55 mg/dL) for patients with history of heart attacks."

  • My coronary calcium score was 232. Do I need to have a stent placed in my arteries?

    "The coronary calcium score is a marker of plaque in the arteries of your heart. It helps us know how aggressive we need to be with medication or lifestyle changes but does not help us decide if you need procedures performed."

  • I had labs and I saw that my lipoprotein(a) was elevated. Should I be freaking out?

    " Lp(a) increases the risk of heart attacks, strokes, and other cardiovascular issues such as aortic stenosis. We are still learning about it. If it is high, your doctor might start paying closer attention to your risk factors and start treatment earlier."

  • I feel a weird sensation in my chest, I was told it could be atrial fibrillation.

    "Atrial fibrillation is a very common arrhythmia that increases the risk for having fast heart rate and strokes, hence we use medications to prevent both. Using procedures to treat it is also an option."

  • What do people really mean by healthy diet?

    "Avoid simple carbohydrates (sweets, sodas, rice, pasta, potatoes, tortillas, arepas…) and “bad” fats (butter, bacon – animal fat). Favor lean protein (grilled fish, chicken) and vegetables. Watch the salad dressings as well."

  • Is there such a thing as too much exercise? I heard that marathons are not good for you.

    "Going past your limits for prolonged periods of time (such as marathons and triathlons) is probably not good for your heart and joints. Be as active as you can, without overdoing it."

  • I Had a Heart Attack 3 Years Ago but I Can't Take Any of the Statins Prescribed

  • I'm Getting a Stress Test but My Doctor says I Don't Have to Run on a Treadmill

  • I’m A 38-Year-Old Woman with Stomach Cramps That Move to My Chest

  • My Doctor Says I Need Quadruple Bypass Surgery. Why Can’t I Have Stents Instead?

  • I’m 65 And I Have Been Taking Aspirin for A Long Time. I Read Aspirin Doesn’t Do Anything. Can I Stop It?
