This is typically secondary to stroke, injury, or cardiac arrest due to heart attack. Most ischemic neurons that die do so due to the activation of chemicals produced during and after ischemia. [2] The ischemic cascade usually goes on for two to three hours but can last for days, even after normal blood flow returns. [3]
Angina, also known as angina pectoris, is chest pain or pressure, usually caused by insufficient blood flow to the heart muscle (myocardium). [2] It is most commonly a symptom of coronary artery disease. [2] Angina is typically the result of partial obstruction or spasm of the arteries that supply blood to the heart muscle. [3]
Angina comes from the latin angere, which means to strangle, and pectoris comes from pectus, meaning chest—so angina pectoris loosely translates to “strangling of the chest”, which actually makes a lot of sense, because angina pectoris is caused by reduced blood flow which causes ischemia to the heart muscle, or lack of oxygen to the ...
Patients at high risk for cardiovascular disease-related medical events should strongly consider taking a statin to reduce their bad cholesterol and lower their future risk of a heart attack or ...
Complications of reflex syncope include injury due to a fall. [1] Reflex syncope is divided into three types: vasovagal, situational, and carotid sinus. [2] Vasovagal syncope is typically triggered by seeing blood, pain, emotional stress, or prolonged standing. [11] Situational syncope is often triggered by urination, swallowing, or coughing. [2]
Coronary artery disease (CAD) occurs when fatty substances, known as plaques, adhere to the walls of coronary arteries supplying the heart, narrowing them and constricting blood flow, a process known as atherosclerosis, the most common cause of coronary ischemia. [25] Angina may start to occur when the vessel is 70% occluded. [9]
Variant angina is caused by vasospasm, a narrowing of the coronary arteries due to contraction of the heart's smooth muscle tissue in the vessel walls. [3] In comparison, stable angina is caused by the permanent occlusion of these vessels by atherosclerosis, which is the buildup of fatty plaque and hardening of the arteries. [4]
Chris Kirmsse learned her coronary artery disease is hereditary, which made some of the deaths in her family make more sense. The mother and daughter hope Chris Kirmsse's story encourages people ...
