A stroke, also known as a cerebrovascular accident or CVA is when part of the brain loses its blood supply and the part of the body that the blood-deprived brain cells control stops working. This loss of blood supply can be ischemic because of lack of blood flow, or hemorrhagic because of bleeding into brain tissue.

Aneurysms increase the risk of blood clots, which could lead to a heart attack or cause life-threatening internal bleeding. For a very small percentage of children who develop coronary artery problems, Kawasaki disease can cause death, even with treatment.

There are multiple causes of second-degree Mobitz type 2 (Wenckebach) AV block, including reversible ischemia, myocarditis, increased vagal tone, status post-cardiac surgery, or even medications that slow AV nodal conduction (e.g., beta-blockers, non-dihydropyridine calcium channel blocks, adenosine, digitalis, and ...

The cause is not fully understood, but it tends to affect certain groups of people, such as those over 65. It may be triggered by certain situations, such as drinking too much alcohol or smoking. Atrial fibrillation can be defined in various ways, depending on the degree to which it affects you.

PVCs rarely cause problems unless they occur again and again over a long period of time. In such cases they can lead to a PVC-induced cardiomyopathy, or a weakening of the heart muscle from too many PVCs. Most often, this can go away once the PVCs are treated.

Chronic venous insufficiency (CVI) is a condition that causes swollen feet due to damaged valves or from standing or sitting for extended periods. This affects blood moving up to your heart from your legs and feet. Blood can collect in the veins of your legs and feet, which leads to swelling.

A racing heart Most types of SVT aren't dangerous on their own. One type of SVT, atrial fibrillation, can be dangerous because it can lead to blood clots, which increase stroke risk. Vagal maneuvers like splashing your face with cold water or coughing can slow down a rapid heartbeat.

Some studies have shown that certain types of CAAs can run in families, but doctors have not yet found a solid pattern to say for sure that CAAs may be hereditary. Coronary artery anomalies are found in about 5% of people who undergo cardiac catheterization to find out why they are having chest pain.

It is also known as cerebral infarction or stroke. Rupture of an artery with bleeding into the brain (hemorrhage) is called a CVA, too. If the symptoms are temporary, usually lasting less than an hour without permanent brain damage, the event is called a transient ischemic attack (TIA).

This happens because when the valve leaks, it can cause the atrium to enlarge. An enlarged atrium may lead to heart rhythm problems such as atrial fibrillation, which may cause blood clots to form. When clots travel from the heart to the arteries or the brain, it can lead to a stroke or heart attack.

If you have rheumatoid arthritis, you're at a higher risk of developing cardiovascular disease (CVD). CVD is a general term that describes conditions affecting the heart or blood vessels, and it includes life-threatening problems such as heart attack and stroke.

Clinical trials have shown that anticoagulation with vitamin K antagonists (VKAs), e.g. warfarin, decreases the risk of stroke in patients with atrial fibrillation (AF); however, increased bleeding risk is one of the safety concerns.

Heart attack may happen when a coronary artery is blocked suddenly, which stops the flow of blood to your heart muscle. Cardiomyopathy is damage to your heart muscle. It can be caused by artery or blood flow problems, infections, and alcohol and drug abuse. Other diseases or genetic issues can also bring it on.

Mitral valve regurgitation can cause complications such as: Atrial fibrillation, in which the atria of the heart don't contract well. This leads to increased risk of stroke. Elevated blood pressure in the lungs (pulmonary artery hypertension)

SVT can become a problem requiring treatment if it lasts a long time or causes shortness of breath or chest pain. Though most episodes of SVT are caused by the heart's electrical system, other causes include certain drugs, health conditions, surgery and familial disorders, such as Wolff-Parkinson-White syndrome.
