My mom was suffered from Inferior MI and she was thrombolysed. Now her general condition is fair. Her BP is maintained at 110/80 mmHg and her heart rate is round about 65.She has no DM and Hypertension. But her cholesterol level was higher than normal. But now within normal limit.Now, cardiologist gave her metoprolol 100 mg bd , aspirin, clopilet, atovarstain 20 mg hs , ivabaradine 5mg half bd and monotrate bd and multivitamins. Her EF is normal and there are no abnormal wall movement on Echo though there are mild MR and TR with left ventricular hypertrophy. Her coronary angiogram shows that there are severe stenosis in LAD and RCA and moderate stenosis in circumflex artery. Plus her CAC is more than 400. Should she be undergone bypass or PCI? I wanna know which option will be best for her. Please answer my question. Thank you in advance.
