Symptoms may include:įor dangerous arrhythmias, doctors may insert a device called a pacemaker to restore a regular heart rate. It may present as a heartbeat that is too quick, too slow, or has a distinctive pattern. medications to manage blood pressure or cholesterol levelsĪn arrhythmia is an abnormal heart rhythm.lifestyle changes, such as dietary and exercise changes.But treatments can help to slow the progression of the disease and alleviate symptoms. personal history of one of the following conditions:.Heart failure occurs when the heart is unable to pump enough blood to satisfy the body’s needs. medications called statins to reduce levels of cholesterol in the blood.antiplatelet or anticoagulant medications to help prevent the formation of new blood clots.A person who experiences a hemorrhagic stroke may require surgery to fix the blood vessel that is bleeding out.įollow-up treatments for stroke may include: A person who experiences ischemic stroke may receive medications to help break up the blood clot and restore blood flow to their brain. The treatment for stroke will depend on the type. dizziness, loss of balance, or difficulty walking.difficulty speaking or understanding speech.one-sided weakness or numbness of the leg, arm, or face.Symptoms of a stroke begin suddenly and may include: Some significant risk factors of a stroke include: Hemorrhagic stroke occurs as a result of a bleed in or around the brain. Ischemic stroke occurs as a result of a blood clot blocking blood flow to the brain. This lack of blood supply triggers the death of brain cells. reaching or maintaining a moderate weightĪ stroke is a medical condition in which the blood supply to a part of the brain becomes cut off.People who have had a heart attack can lower their chances of future cardiovascular problems by engaging in the following: Three of the main risk factors of a heart attack are: pain or discomfort in one or both arms or shoulders. ![]() pain or discomfort in the jaw, neck, or back.This can occur due to a blockage, a tear in an artery around the heart, or if the heart requires more oxygen than is available. Heart attackĪ heart attack happens when a part of the heart muscle does not receive enough blood. Overviews of some common cardiovascular diseases are below. Understanding conditions that can affect the cardiovascular system may help people seek appropriate and timely medical advice. The left ventricle pumps the blood through the aortic valve into a large artery called the “aorta.” This artery delivers blood to the rest of the body.Ĭommon diseases of the cardiovascular systemĬardiovascular diseases can be severe and potentially life threatening.Blood flows through the mitral valve and enters the left ventricle (lower left chamber).The blood returns to the heart and flows into the left atrium (upper left chamber) via four pulmonary veins.As a result, the blood is now rich in oxygen. Here, the process of breathing draws oxygen into the blood and removes carbon dioxide. The blood then flows through the left and right pulmonary arteries into the lungs.The right ventricle pumps blood through the pulmonary valve and out of the heart via the main pulmonary artery.Blood flows through the tricuspid valve and enters the right ventricle (lower right chamber).Blood lacking oxygen returns from the body and enters the right atrium (upper right chamber) via the inferior vena cava and superior vena cava veins.Valves control the flow of blood within the different chambers.īlood follows the following path through the heart: The heart consists of four distinct chambers: two upper chambers called “atria” and two lower chambers called “ventricles.” A wall or “septum” separates the atria and ventricles.
