Formation of plaque (fatty deposits) clogs is called atherosclerosis. Atherosclerosis is a condition that develops when a substance known as plaque builds up within the walls of the arteries. This buildup narrows the arteries, creating it harder for blood to flow through. If a blood clot forms, it will block the blood flow. This could cause an attack or stroke.
Journal Cardiology focuses on the topics that include but not limited:
Coronary artery Disease:
Coronary artery disease also known as ischemic heart disease refers to a group of diseases which includes stable angina, unstable angina, myocardial infarction, and sudden cardiac death. A common symptom is symptom is pain or discomfort which can travel into the shoulder, arm, back, neck, or jaw. Usually symptoms occur with exercise or emotional stress, last less than a few minutes, and improve with rest.
Heart arrhythmia is conditions in which the heartbeat shows irregularities like beating too fast, or too slow. A heart rate above 100 beats per minute in adults is called tachycardia and a heart rate below 60 beats per minute is called bradycardia. Many types of arrhythmia have no symptoms. Symptoms may include palpitations or feeling a pause between heartbeats. In serious cases there may be lightheadedness, passing out, shortness of breath, or chest pain.
Atrial fibrillation or AF is the most common type of arrhythmia. AF occurs if rapid, disorganized electrical signals because the heart's two upper chambers - called the atria to fibrillate. The term "fibrillate" means to contract very fast and irregularly. The term "fibrillate" means to contract very fast and irregularly. In AF, blood pools in the atria. It isn't pumped completely into the heart's two lower chambers, called the ventricles. As a result, the heart's upper and lower chambers don't work together as they should. If AF is unnoticed, it can increase the risk of stroke. In some people, AF can cause chest pain or heart failure, especially if the heart rhythm is very rapid.
Hypercholesterolemia is a condition characterized by very high levels of blood cholesterol. Cholesterol is a waxy, fat-like substance that is produced in the body and obtained from foods that come from animals (particularly egg yolks, meat, poultry, fish, and dairy products). The body needs this substance to build cell membranes, make certain hormones, and produce compounds that aid in fat digestion. Too much of cholesterol, however increases a person's risk of developing heart disease. People with hypercholesterolemia have a high risk of developing a form of heart disease called coronary artery disease. This condition occurs when excess cholesterol in the bloodstream is deposited in the walls of blood vessels, particularly in the arteries that supply blood to the heart (coronary arteries). The abnormal buildup of cholesterol forms clumps (plaque) that narrow and harden artery walls. As the clumps get bigger, they can clog the arteries and restrict the flow of blood to the heart. The buildup of plaque in coronary arteries causes a form of chest pain called angina and greatly increases a person's risk of having a heart attack.
Cardiology is a branch of medicine which deals with the disorders of the heart in humans or animals. The field includes medical diagnosis and treatment of congenital heart defects, coronary artery disease, heart failure, valvular heart disease and electrophysiology. Physicians who specialize in this field of medicine are called cardiologists, a specialty of internal medicine. Pediatric cardiologists are pediatricians who specialize in cardiology. Physicians who specialize in cardiac surgery are called cardiothoracic surgeons or cardiac surgeons, a specialty of general surgery. Medicines given by these cardiologists for the treatment purpose of cardiac related diseases are cardiovascular medicines.
