What is the Polypill?

Dr. Valentin Fuster discusses the Polypill. The Polypill is being developed in response to an important reality surrounding cardiovascular disease. There are three important drugs that can help prevent heart disease (statins, ACE inhibitors, and aspirin). These drugs are not taken for two major reasons. First, the drugs are simply too expensive for much of the world, including countries as developed as Russia. And secondly, in developed nations where the drugs are affordable patients too often fail to comply - after three years 70% of patients do not take the medications as prescribed.

What Are the Risk Factors of Coronary Artery Disease?

Dr. Valentin Fuster discusses the 6 causes or risk factors behind coronary artery disease. There are two physical risk factors: high blood pressure and size of the waist (or abdominal obesity). There are two chemical risk factors: cholesterol levels in the blood and blood glucose (diabetes). And finally, there are two lifestyle risk factors: smoking and exercise.

What is Coronary Artery Disease?

Dr. Valentin Fuster, one of the world's leading cardiologists, discusses the basics of coronary heart disease. Dr. Fuster than describes the symptoms of a heart attack and how to differentiate these symptoms from other conditions. Most importantly, he urges viewers to pay attention to these symptoms and the importance of getting medical treatment as soon as possible, even if one has the least suspicion of a coronary incident. Getting treatment in the first hour or two can minimize damage to heart muscle.

What is Peripheral Arterial Disease?

Dr. Sattesh Babu of Vascular Associates of Westchester discusses Peripheral Arterial Disease, who is at risk, why it is important to be screened and current treatments. Pad is essentially a blockage of the arteries in the lower extremities. That is what we mean by peripheral arteries -- leg arteries blocked by hardening of the arteries, buildup of cholesterol, plaque and calcium. This in part is a process of aging, but certainly also brought on by smoking. Diabetes is another risk factor, as is hypertension.

What is Carotid Stenosis?

Women, Obesity Rates, and the Fountain of Youth

The fattening of America is so out there, so obvious, the question has become how do we get the message that we need to reverse the trend? Perhaps, the message is sinking in, at least among women. New research released by the CDC shows, among women, no significant increase in obesity was observed between 1999 and 2004…roughly a third of females remain obese

Work Stress and Metabolic Syndrome

It would make sense at first glance that workplace stress leads to heart disease--no surprise, right? But the latest research shows chronic stress at work can also leads to diabetes--and that--raises eyebrows. “Deadlines, they ask you questions all the time, is this done yet, is that done yet,” cries Esteban Chavez. Do you ever feel like work just wants to make you scream?!

Heart CAT Scans

Fast heart CAT scans have been a screening test in limbo. The exact role and place for this exam, which is becoming more widely available, hasn't been well defined, until now.

Sudden Death Predictor

Sudden cardiac death is one of the leading causes of mortality in America. Now, new research points to a way to identify those most at risk--and it involves a simple exercise test. The frustration lies in the name of the problem. Sudden cardiac death is sudden because it's typically the first sign or symptom that an individual has a heart problem. And, often, sadly, it's the last.

Understanding the Internal Structure of the Heart

The Internal Structure of the Heart. A muscular septum divides the heart internally into a left and a right half. Each half is subdivided into two chambers, the atrium (reception) and the ventricle (pump chamber). Internally all four chambers have a smooth membranous lining, the endocardium.
