Hello @bermuda , as @kanaazpereira mentioned, I had a period of time where I encountered several health issues all within a seemingly short period of time. It all started with a heart attack at age 48, an episode of V-tach while in the ICU recovering from the heart attack, a couple of ischemic cerebellar strokes a couple weeks later, low EF as a result of heart damage, discovery of PFO hole, and then a bout with seizures. The seizures took me by surprise as they were about 18 months after the heart attack occurred, and by then I thought I had all under control. Because of the low EF, the cardiologist suggested several preventative options, "just in case" to potentially thwart other episodes. The ICD was suggested to be implanted in case my heart decided to go into ventricular tachycardia and would be there to shock my heart back into normal rhythm should it not return on its own. The PFO closure procedure was suggested as I they could see some bubbles passing through during the echo with IV contrast. With both the hole and low EF, the concern is that of a clot forming. I am on warfarin for life to also help prevent further clot formation and the likelihood of another stroke. I've not had any problems or issues resulting from the PFO closure. My seizures have been controlled with medication (Kepra). I've been issue free until late last year when my ICD fired off twice. Once while I was sleeping and I ddn't even know it happened until the device clinic called me and asked if I was doing ok. The second time it went off I was shoveling really heavy/wet snow. At that point, the cardiologist scheduled a visit and we discovered I was in a-fib. Had an electro cardioversion procedure done and since then in combination with some new meds, the a-fib has stayed away. The point of describing all this is; over 6 years ago prevention 'options' were provided and I am thankful I chose them. If it weren't for the ICD, I wouldn't be here today. The others in combination with meds I know have helped me from encountering any other issues. Of course there is not guarantee I won't suffer another stroke at some point down the road, but for now I am doing everything I can to minimize that risk. This year I turn 55 and I feel I'm in better health than I was leading up to my heart attack 7 years ago. Are you on any sort of blood thinner? I wish you well!
