Back

• Decreased cardiac output leading to fulminant congestive heart failure (CHF)
• Ventricular and A-V block dysrhythmias
• Ventricular rupture or aneurysm usually followed by cardiogenic shock
• Papillary muscle rupture associated with the inferior wall MI and mitral regurgitation
• Acute ventral septal defect requiring surgical repair
• Puncture of a coronary artery during catheterization may induce cardiac tamponade: cardinal signs include pulsus paradoxus (widening pulse pressure) and muffled heart sounds leading to cardiovascular collapse
• Global hypo-perfusion, leading to myocardial stunning and cardiogenic shock
• Late: pericarditis as evidenced by global ST segment elevations, new onset friction rub, and aching chest pain not relieved by nitrates
