3 Major symptoms of Coronary Artery Disease
March 26, 2021
Coronary Artery Disease (CAD) is the damage, deterioration or blockage of the coronary arteries that are located on the heart. The coronary arteries are the main arteries that supply oxygen and nutrients to the cardiac tissues. If these arteries are damaged or blocked, the cells of the heart lack enough oxygen or nutrients to carry out basic biological processes leading to cardiac muscle damage. CAD is a result of coronary arteriosclerosis (a gradual process of the inner lining of the artery wall getting damaged and subsequent buildup of plaque at the site). If not treated in time and diagnosed correctly, CAD can lead to several potentially fatal cardiovascular problems like myocardial infarction (or heart attack).

Life after Aortic Valve Replacement
March 23, 2021
Aortic stenosis is regarded as one of the most common, yet serious valve disease problems. It refers to the narrowing of the aortic valve's opening. This critical condition restricts the flow of the blood from the left ventricle to the aorta. It may also affect the pressure within the left atrium. Some people suffer from aortic stenosis owing to a congenital heart defence known as a bicuspid aortic valve. For most others, this serious medical condition typically develops as one begins to age. With age, the valves are damaged by calcium or scarring, thus restricting the blood flow.

Drug Eluting Stent: What is It & How It is Implanted? | Meril Life
March 17, 2021
A stent is a tiny, metal mesh tube or a scaffold-like device designed to support the artery walls and prevent plaque from blocking the blood flow. Once the doctor implants the stent in an artery, the blood flows more freely to the part of the patient's heart which that artery was supposed to supply blood to. A drug-eluting stent or DES is a metal stent coated with a pharmacologic agent or drug. This type of stent is known for suppressing restenosis, i.e. the closing up or re-blocking of an artery after an angioplasty as a result of excess tissue growth at the edge of or inside the stent. In modern practice, most patients are treated with such drug eluting stents.
