The DASH diet (Dietary Approaches to Stop Hypertension) is a dietary pattern promoted by the U.S.-based National Heart, Lung, and Blood Institute (part of the National Institutes of Health, an agency of the United States Department of Health and Human Services) to prevent and control hypertension....

A palpitation is an abnormality of heartbeat that ranges from often unnoticed skipped beats or accelerated heartrate to very noticeable changes accompanied by dizziness or difficulty breathing. Heart palpitations can be symptoms of illnesses such as coronary heart disease, asthma, emphysema. Patients...

Cardiac dysrhythmia (also known as arrhythmia or irregular heartbeat) is any of a large and heterogeneous group of conditions in which there is abnormal electrical activity in the heart. The heartbeat may be too fast or too slow, and may be regular or irregular. A heart beat that is too fast is called...

Pulmonary and tricuspid valve diseases are right-side heart diseases. Pulmonary valve diseases are the least common heart valve disease in adults. The most common types of pulmonary valve diseases are: pulmonary valve stenosis pulmonary valve insufficiency pulmonary valve incompetence pulmonary...

Vangina pectoris–commonly known as angina–is chest pain do to ischemia of the heart muscle, generally due to obstruction or spasm of the coronary arteries.[1] The main cause of Vangina pectoris is Coronary Artery Disease, due to atherosclerosis of the arteries feeding the heart. The term derives...

Breast cancer is a type of cancer originating from breast tissue, most commonly from the inner lining of milk ducts or the lobules that supply the ducts with milk. Cancers originating from ducts are known as ductal carcinomas, while those originating from lobules are known as lobular carcinomas....

Although in theory the term "cardiomyopathy" could apply to almost any disease affecting the heart, in practice it is usually reserved for "severe myocardial disease leading to heart failure". Cardiomyopathies can be categorized as extrinsic or intrinsic. An extrinsic cardiomyopathy...

Coronary heart disease (CHD) is the narrowing or blockage of the coronary arteries, usually caused by atherosclerosis. Atherosclerosis (sometimes called “hardening” or “clogging” of the arteries) is the buildup of cholesterol and fatty deposits (called plaques) on the inner walls of the arteries....

The carotid artery is the large artery whose pulse can be felt on both sides of the neck under the jaw. On the right side it starts from the brachiocephalic trunk (a branch of the aorta) as the common carotid artery, and on the left side the common carotid artery comes directly off the aortic arch....

A heart block is a disease in the electrical system of the heart. This is opposed to coronary artery disease, which is disease of the blood vessels of the heart. While coronary artery disease can cause angina (chest pain) or myocardial infarction (heart attack), heart block can cause lightheadedness,...

The long QT syndrome (LQTS) is a rare inborn heart condition in which delayed repolarization of the heart following a heartbeat increases the risk of episodes of torsade de pointes (TDP, a form of irregular heartbeat that originates from the ventricles). These episodes may lead to palpitations, fainting...

Melanoma (from Greek μέλας — melas, "dark") is a malignant tumor of melanocytes. Melanocytes are cells that produce the dark pigment, melanin, which is responsible for the color of skin. They predominantly occur in skin, but are also found in other parts of...

Skin cancers (neoplasms) are named after the type of skin cell from which they arise. Basal cell cancer originates from the lowest layer of the epidermis, and is the most common but least dangerous skin cancer. Squamous cell cancer originates from the middle layer, and is less common but more likely...

An aneurysm or aneurism (from Greek: ἀνεύρυσμα - aneurusma "dilation", from ἀνευρύνειν - aneurunein "to dilate") is a localized, blood-filled balloon-like bulge in the wall of a blood vessel. Aneurysms can commonly occur in arteries at the base of the brain...
