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...

Aortic Valve Implantation for Valvular Heart Diseases
The human heart has four valves – mitral, tricuspid, aortic and pulmonary. The main function of these heart valves is to ensure the one-way blood flow throughout the heart’s chambers. Mitral and tricuspid valves take control of flow of blood into the ventricles. Pulmonary valves allow blood flow to the pulmonary artery....

Treating Atrial Fibrillation with Vitamin K Antagonist Therapy
Blood to the heart muscles is supplied by the coronary arteries and the entire pumping process is controlled by the heart’s electrical conduction system. Any disruption to the electrical signal transmission affects the blood flow and functioning of the heart. Whenever there is an obstruction in the blood supply, the heart muscles become starved of oxygen and nutrients, which leads to more chest pain or discomfort. Atrial fibrillation
(AF)...

Percutaneous Coronary Intervention in Managing Acute Coronary Syndromes
Damage of the
heart muscles due to inadequate blood flow or oxygenation is known as myocardial ischemia. The condition becomes worse in some cases, resulting in myocardial infarctions (heart attacks) or unstable angina. Atherosclerotic plaque build up in the coronary arteries is the main cause of restriction in the blood supply. Termed as Coronary Artery Disease (CAD) or coronary heart disease, this condition has been a leading cause of mortality...

Barostim Therapy & Cardiovascular Health
Whenever there is an obstruction or blockage in the coronary arteries, it hinders the oxygen-rich blood flow to the heart muscles, resulting either in angina (chest pain) or myocardial infarctions (heart attacks). In some cases, the blockage occurs more slowly so that collateral circulation starts to take up the role of...

Stenting For Multivessel Coronary Artery Disease
Hardening of arteries (atherosclerosis) not only causes lesions in the blood vessels but also results in the obstruction of blood supply to the heart muscles. During strenuousactivities, narrowed coronary arteries won’t be able to supply enough blood to the myocardium leading to angina (chest pain). Coronary artery disease...

FFR-Guided Percutaneous Coronary Intervention Gain Advantage Over Medical Therapy
Coronary heart disease also known as ischemic heart disease can be described as a condition where the coronary arteries are severely narrowed because of atherosclerosis. When the heart muscle is starved of oxygen and nutrients, it induces chest pain (angina). However, in some cases there is a complete blockage in blood supply leading to heart muscle damage and myocardial infarctions (heart attacks). Some of the common symptoms of coronary artery...

Treatment of Coronary Bifurcation Lesions
Interventional
cardiology has been witnessing technological advances and improved success over the last decade. Increasing success and safety levels of interventional cardiac procedures has improved the outcomes for patients with coronary artery disease (CAD). An underlying pathologic process called atherosclerosis can make...

Fractional Flow Reserve Measurement For Assessing Coronary Stenosis
Coronary Heart Disease which occurs as a result of atherosclerotic plaque-build up in the inner walls of coronary arteries is a common heart ailment that has been affecting millions of people worldwide. The field of cardiac science and interventional cardiology has been striving hard to devise an optimal approach to manage coronary artery disease (CAD). Evaluating the physiological significance and severity of lesions is a challenging factor...

Left Main Coronary Artery Stenting – Is it a Safe Approach?
Common coronary heart disease (CHD) also to referred as ischemic heart disease is the leading cause of heart attacks and angina. Atherosclerotic plaque build-up in the inner walls of coronary arteries hardens the blood vessels and restricts the blood supply to heart. Lack of oxygen leads to the damage or death of heart...

Advanced Diagnostic & Treatment Options for Cardiac Artery Disease Management
Stress testing is a widely used non-invasive diagnostic method that provides reliable information about the severity of symptomatic cardiac artery disease or coronary artery disease (CAD). As the name indicates, stress testing is carried out by putting the body under physical stress. A myocardial perfusion scan is a combined procedure that combines stress testing and a nuclear heart scan.
Myocardial perfusion scan is a non-invasive cardiac imaging...
