When someone dies suddenly with only a large heart -- concentric oreccentric hypertrophy, and the medical examiner finds no other cause of death,it's considered acceptable to blame a rhythm disturbance(NEJM 358: 1370, 2008 -- the article makes the point that in athletic/physiologicalhypertrophy, you do NOT get rhythm problems as a result).
Coronary heart disease is one of the diseases grouped with cerebrovascular disease and peripheral artery disease under the group heading, cardiovascular disease....
Some of the most common types of heart disease include heart attack, which occurs when part of the heart dies due to lack of oxygen, coronary stenosis, which is the narrowing of vessels that supply the heart itself with blood, angina, which is discomfort due to decreased oxygen to the he...
Coronary heart disease (CHD) is caused by atherosclerosis which occurs when the build-up of cholesterol in the arterial wall limits the travel of oxygen-rich blood in the body3.
The heart pumps blood around the body carrying oxygen and other essential nutrients to the areas in the body where they are needed.1 Coronary Heart disease is when this process is restricted or interrupted.
It helps if the patient has a history of "high blood pressure", but when congestive heart failure supervenes on the salt-overloaded, hyper-constricted vascular system, "the high blood pressure may be cured".
if you are reasonably fit, you areprobably not going to have a heart attack during sex, but if you're a heart patient and out of shape and then goexercise and/or have sex, you're in danger (JAMA 305: 1225, 2011).
It's now painfully clear that a person's successful return to near-normal living after a heart attack is largely a function of his or her knowledge about the disease.
Serious degrees of HEART BLOCK can cause people with coronary disease (or other problems; remember amyloid) to drop over suddenly ("Stokes-Adams attacks", etc.) Get them pacemakers.
* NOTE: Somebody may tell you that most congestive heart failure in the elderly is due tocoronary atherosclerosis, even in the absence of ischemic scarring, and that the ischemia causes the hypertrophy.
Worth remembering: ATRIAL FIBRILLATION is a troublesome rhythm disturbanceaffecting about 3 million people in the US, seen in coronary disease,mitral valve disease (why?), hyperthyroidism (George Bush Sr.; why?), ectopic (and ablatable) foci in the pulmonary veins(NEJM 339: 659, 1998; now mainstream NEJM 354: 934, 2006), etc.
NOTE: The other major causes of sudden unexpected naturaldeath are pulmonary emboli,pulmonary hypertension (idiopathic or in chronic lung disease),anaphylaxis, brain hemorrhages, and epileptic seizures ("SUDEP"; "Jett Travolta's disease"; Lancet 378: 2028, 2011; Neurology 57:430, 2001; Neurology 64: 1131, 2005; NEJM 365: 1801, 2011; future medicalexaminers see Am.

Any right-heart problem resulting from increased pulmonary vascular resistance (usually poor ventilation, less often fibrosis or primary vascular problems).
