Why MI is a trajectory disease, not an accident
The MI occurs as acute event — atherosclerotic plaque ruptures, thrombus occludes a coronary artery, myocardial ischemia, necrosis. But the atherosclerosis culminating in that event builds 20 to 30 years earlier: dyslipidemia with elevated ApoB, sustained HTN, hyperglycemia, vascular inflammaging, endothelial damage, smoking. The event is the visible consequence of a silent trajectory.
INTERHEART (Yusuf et al., Lancet 2004, n=15,152 cases vs 14,820 controls in 52 countries) quantified something decisive: 9 modifiable factors (dyslipidemia, smoking, HTN, diabetes, abdominal obesity, psychosocial stress, diet, exercise, alcohol) explain 90% of population MI risk. That figure leaves no margin: primary prevention works, and the window is decades long.
MI is not an accident. It is the visible consequence of 30 years of biology that could be measured and modulated earlier.
