Most people with the condition develop symptoms before they are 40 years old. [6] It is a relatively common cause of sudden death along with Brugada syndrome and arrhythmogenic right ventricular dysplasia. [3] In the United States it results in about 3,500 deaths a year. [6] The condition was first clearly described in 1957. [10]
In 20% of cases, no cause of death can be found, even after extensive examination. [13] Sudden arrhythmic death syndrome in alcohol abuse is a significant cause of death among heavy drinkers, characterized by older age and severe liver damage, highlighting the need for family screening for heritable channelopathies. [4]
As a genetic syndrome, those affected are born with the condition. Symptoms can occur in newborns, potentially presenting as sudden infant death syndrome. [2] Males and females are equally likely to be affected, and have a similar risk of sudden cardiac death. [2]
Reduced body temperature, or therapeutic hypothermia, during clinical death slows the rate of injury accumulation, and extends the time period during which clinical death can be survived. The decrease in the rate of injury can be approximated by the Q 10 rule, which states that the rate of biochemical reactions decreases by a factor of two for ...
Based on death certificates, sudden cardiac death accounts for about 20% of all deaths in the United States. [ 151 ] [ 152 ] In the United States, approximately 326,000 cases of out-of-hospital and 209,000 cases of IHCA occur among adults annually, which works out to be an incidence of approximately 110.8 per 100,000 adults per year.
Symptoms may worsen over the course of several minutes. [4] Typical angina is aggravated by physical activity or emotional stress and is relieved by rest or nitroglycerin. [4] The pain may radiate to other parts of the body, most commonly the left arm or neck. [7] In some individuals, the pain may be less severe and present as pressure or ...
The ECG should be done as early as practicable, including in the ambulance if possible. [18] ECG changes indicating acute heart damage include: ST elevation, new left bundle branch block and ST depression amongst others. The absence of ECG changes does not immediately distinguish between unstable angina and NSTEMI. [6]
Symptoms include chest pain, shortness of breath, pain in upper body, fatigue, nausea, an irregular heartbeat, and drowsiness. [ 5 ] To diagnose a coronary occlusion, a doctor may view a patient's medical history, or perform a coronary angiography; a doctor will stick a catheter into the wrist or groin, lead it to the heart, and inject a liquid ...
