On their own, just being angry or exercising in a neutral state doubles your risk of a heart attack. Out of all the heart attack cases studied, 14 percent of the victims had been angry during the ...
A heart attack results from a sudden plaque rupture and formation of a thrombus (blood clot) that completely blocks blood flow to a portion of the heart, leading to tissue death . CAD can also result in heart failure or arrhythmias. Heart failure is caused by chronic oxygen deprivation due to reduced blood flow, which weakens the heart over time.
