A 52-year-old man from Delhi presents to the emergency department with acute onset chest pain radiating to the left arm for 3 hours. His blood pressure is 95/60 mmHg, heart rate 110/min, and respiratory rate 24/min. ECG shows ST elevation in leads II, III, and aVF. Troponin I is elevated at 2.8 ng/mL. He is immediately taken for primary PCI. Coronary angiography reveals complete occlusion of the right coronary artery, which is successfully revascularized. Tissue samples obtained during the procedure show myocardial cells with preserved cell membrane integrity, intact organelles, and absence of inflammatory infiltrate. Which type of cell death is predominantly occurring in the salvaged myocardium immediately after reperfusion?
