Hi. Thank you for your question and welcome to HCM. I carefully read your query.
I would open my answer by giving you an information regarding stents. A bare metal stent (BMS) has a 16-20% rate of narrowing, whereas a
drug-eluting stent (DES) has a 4% rate of narrowing. I think that you were advised, on discharge, to have periodical cardiac stress tests, 1, 3 and 6 months after the
stent implantation. My opinion is that if these symptoms are of high intensity and severity, and/or similar with the ones that heralded the
heart attack, you should conuslt your cardiologist and consider performin another coronary angiogram to see how the stents are doing.
As about the dry cough, I assume your father is on a drug from the class of angiotensinogen converting enzyme inhibitors (ACE-I: captopril, enalapril,
lisinopril), which produce cough as a side effect in 10-15% of subjects that use it. If this is the case, I would recommend changing this drug with a drug from the angiontensin receptor blocker (ARB: losartan,
valsartan, eprosartan) class. The dry cough should subside in three weeks.
I hope I was helpful. Best regards.
