Narrowing of the coronary arteries due to the build-up of atherosclerotic plaque in the inner walls of blood vessels restrict the blood supply to heart muscles resulting in coronary heart disease (CHD). Though pressure wire guided percutaneous coronary interventions and surgery procedures are used to treat CHD, the initial treatment goal is to reduce the risk factors. High blood pressure is considered as a major risk factor of coronary artery disease...

What Causes Acute Myocardial Infarction?
Coronary arteries supply oxygen-rich blood and nutrients to the heart muscles, thereby keeping it nourished and healthy. Whenever the heart has to work harder, it needs more oxygen. For instance, during exercise, the heart starts to beat faster thereby increasing oxygen demand on the heart. The only way to keep up with...

Treating Cardiac Arrhythmias with Catheter Ablation
Rhythmic sequence of the heart beat is controlled by the precise generation and flow of electrical impulses. Any disruption in the functioning of the heart’s electrical system causes the heart to beat abnormally. A condition characterised with irregular heartbeats or abnormal heart rhythm is called cardiac arrhythmia (dysrhythmia)....

What Is Hyperlipidemia?
Soft and waxy lipid cholesterol has gained a maligned status these days. However, it is essential for building and maintaining cellular membranes, hormone synthesis
and other vital body functions. Since these fat molecules don’t dissolve in the blood stream, they need a special transportation system to travel through the...

Stroke Prevention In Atrial Fibrillation Guidelines
A normal heart beat occurs whenever there is a coordinated progression of electrical impulses. Sinoatrial node (SA node), also known as the heart’s natural pacemaker sends out the electrical impulses which will make the atrium and ventricles contract and push blood throughout the body. Any disruption to this electrical impulse generation and transmission results in symptomatic heart valve disease treatment, abnormal heart rhythms and is termed...
