In certain cases, cardiologists will perform minimally intrusive procedures to treat cardiovascular disease. The Angioplasty procedure uses a tiny mesh tube to hold the artery open while a large balloon opens a blockage. Pacemakers and defibrillators are also options for regulating abnormal heart ...
When your heart doesn’t get the care it needs, serious problems can develop in the lining of the arteries, which then lead to plaque formation. Plaque is what leads to heart attacks and blockage of blood flow in the arteries. Understand the conditions that affect your heart and the habits...
HFrEF models are mainly obtained through surgical procedures, such as transverse aortic constriction, coronary or abdominal artery ligation or constriction, pulmonary artery banding, rapid ventricular pacing, or a combination thereof. Additionally, transgenic animals have also been used to activate the ...
A lacunarstroke, also called a lacunar infarct, occurs when an artery that supplies blood to the deeper portions of the brain becomes blocked. Other types of strokes occur on the surface, or cortex, of the brain. Lacunar strokes represent anywhere from 15% to 25% of strokes. What Is a L...

This stroke occurs when an artery that supplies the brain with blood is blocked. The blockage starves the brain of blood and oxygen. If it is very large, the person can fall into a stupor or coma. In people with diabetes, the body does not produce enough of the hormone insulin. ...

Iron deficiency anemia– When severe, this can lead to blockage of the blood vessels, including central retinal vein occlusion and retinal artery occlusion. In addition, it may cause disc edema — swelling where the retina and optic nerve connect. ...
A blood flow-obstructing clot that develops in a coronary artery can lead to acute coronary syndrome (unstable angina or heart attack), and in a cerebral artery, it can cause a stroke.3,12 An arterial blood clot can also break away from the vessel wall. The dislodged or fragmented blood ...
to the heart, and many women we see in the emergency room don't have blockages in those arteries. Yet, they have everything else that looks like a heart attack: They have the symptoms, the electrocardiogram findings, and the blood test results, but we don't find a major blockage. ...
