If the following events were placed in chronological order which would come fourth?

Chronic pyelonephritis (C) result in systemic hypertension (E) with left ventricular hypertrophy (A); hypertension is associated with increased risk of atheroma and thrombotic occlusion of a coronary artery (B) which causes myocardial infarction, complicated by necrosis of the left ventricular wall and eventual rupture (D).
