Hello. If your mother indeed has heart or myocardial infarction (heart attack), it is extremely serious and she is very lucky to have survived it. She needs urgent treatment as she may not be so lucky next time. After the consultation her physician will ask fir a few blood tests and an ECG and Echocardiogram. She may also require a treadmill test if both the ECG and Echocardiogram donot show any obvious abnormalities. However, as you said, if she has had a heart attack, she will need intervention like angioplasty or possibly a bypass surgery depending on the severity of the blocks. She needs to understand the significance. This condition if ignored, can lead to death or may give rise to other heart conditions like irregular heart beat which may cause a stroke and leave her paralyzed for the rest of her life. Hope she understands the significance and agrees to a hospital visit. Wishing her good health. Regards, Dr Geeta
