The underlying causes of sudden cardiac arrest can result from cardiac and non-cardiac etiologies. The most common underlying causes are different, depending on the patient's age. Common cardiac causes include coronary artery disease, non-atherosclerotic coronary artery abnormalities, structural heart damage, and inherited arrhythmias. Common ...
Although HCM may be asymptomatic, affected individuals may present with symptoms ranging from mild to critical heart failure and sudden cardiac death at any point from early childhood to seniority. [15] [40] HCM is the leading cause of sudden cardiac death in young athletes in the United States, and the most common genetic cardiovascular ...
An irregular heart beat and fainting may occur. [1] Those affected are at an increased risk of sudden cardiac death. [2] As of 2013, cardiomyopathies are defined as "disorders characterized by morphologically and functionally abnormal myocardium in the absence of any other disease that is sufficient, by itself, to cause the observed phenotype."
Common causes of cardiac tamponade include cancer, kidney failure, chest trauma, myocardial infarction, and pericarditis. [2] [5] Other causes include connective tissues diseases, hypothyroidism, aortic rupture, autoimmune disease, and complications of cardiac surgery. [2] [6] In Africa, tuberculosis is a relatively common cause. [1]
In the latter case, the disease creates blockages in the heart's blood supply, leading to tissue death which causes other areas of the heart to work harder, causing the heart to expand in size. [citation needed] Other possible causes include: Heart valve disease; Cardiomyopathy (disease of the heart muscle) [17] Pulmonary hypertension [18]
A heart attack requires immediate treatment to improve blood flow to your heart, relieve your symptoms, and prevent another heart attack. Some treatment options include: Some treatment options ...
In adults and children over 15, resting heart rate faster than 100 beats per minute is labeled tachycardia. Tachycardia may result in palpitation; however, tachycardia is not necessarily an arrhythmia. Increased heart rate is a normal response to physical exercise or emotional stress.
Sudden arrhythmic death syndrome (SADS) is a sudden unexpected death of adolescents and adults caused by a cardiac arrest. However, the exact cause of the cardiac arrest, and thus the exact cause of death, is unknown. These deaths occur mainly during sleep or at rest. [7] One type of conduction defect known as Brugada syndrome can be ...
