Myocardial Infarction Complications conditions
MI Complication (Cardiac Arrhythmia) (First Few Days to Months Post-MI)Cardiac arrhythmias occurring days to months after myocardial infarction result from ischemic injury disrupting electrical conduction and increasing sudden death risk.MI Complication (Interventricular Septal Rupture) (3–5 days Post-MI)A mechanical complication occurring 3–5 days after MI, causing a septal defect that leads to a new harsh systolic murmur and acute heart failure.MI Complication (Myocardial Infarction) (0–24 hours Post-MI)MI complication 0–24 hours post-MI involves early mechanical and electrical issues like arrhythmias, cardiogenic shock, and myocardial rupture causing acute deterioration.MI Complication (Papillary Muscle Rupture) (2–7 days Post-MI)MI complication papillary muscle rupture occurs 2 to 7 days post-MI, causing acute mitral regurgitation due to ischemic muscle necrosis and sudden valve dysfunction.MI Complication (Peri-infarction Pericarditis) (1–3 days Post-MI)Peri-infarction pericarditis occurs 1–3 days after MI due to inflammation of the pericardium near necrotic myocardium, causing chest pain and friction rub.MI Complication (True Ventricular Aneurysm) (2 weeks to months Post-MI)True ventricular aneurysm is a late MI complication occurring 2 weeks to months post-infarct, characterized by scarred, thinned myocardium causing dyskinetic wall motion.MI Complication (Ventricular Free Wall Rupture) (5–14 days Post-MI)Ventricular free wall rupture occurs 5–14 days post-MI due to weakened myocardium, causing sudden tamponade and rapid hemodynamic collapse.MI Complication (Ventricular Pseudoaneurysm) (3–14 days Post-MI)A ventricular pseudoaneurysm is a rare post-MI complication occurring 3–14 days after infarction, caused by myocardial rupture contained by pericardium.
