DOBUTAMINE STRESS ECHOCARDIOGRAPHY (DSE)

Echocardiography uses ultrasound waves (high-frequency sound waves) to assess the motion of the heart muscle and blood vessels.

Dobutamine stress echocardiography (DSE) is a non-exercise stress test that allows the cardiologist to study the capacity and reserve of heart muscle function under stressful condition.

Dobutamine, a cardiac medication, is infused through a vein in increasing doses to stimulate the heart to beat faster and harder. Ultrasound images are then obtained to study the heart’s function during the infusion of dobutamine. These are then compared to the images obtained at rest to determine if any part of heart contracts abnormally.

Heart Healthy Diets - The Mediterranean Diet

Chances are, you have probably heard about the Mediterranean Diet, either in the media or from friends and family. But what is it exactly? It is more of a style of eating than a traditional diet, and top health experts from around the world sing its praise. One of the reasons for this praise is that it is one of the only diets shown to reduce heart attack and stroke in clinical trials (PREDIMED study). The following article will explain the Mediterranean diet, the health benefits of this eating style, and suggestions on following it.

A heart doctor tells why he eats 100g of dark chocolate every week featuring Dr Michael MacDonald

Despite having a “terribly sweet tooth”, heart doctor Michael MacDonald tries to avoid consuming too many sweet and sugary treats for health’s sake. Once a week though, the 44-year-old who professes to be a “big fan of chocolate” permits himself a small bar of dark chocolate.

Improving Your HDL-Cholesterol

High density lipoproteins are important for the transport of cholesterol (collectively known as HDL-C) to the liver for breakdown and removal. In clinical practice, HDL cholesterol, rather than HDL particle structure or function, is used to risk stratify patients. Because these molecules transport cholesterol away from the arteries to the liver, HDL-C is commonly viewed as 'good' cholesterol and has been associated with reduced risk of coronary heart disease.
