Ndugu mtoa mada bila shaka inawezekana hufahamu maana na matumizi ya neno heart attack otherwise u wouldnt have used it here to describe the condition of ur subject
heart attack is a serious medical emergency and carries high mortality even in best centers or well resourced places. However this is not the topic in concern.
kuhusu kuongonoka kwa mtu mwenye heart problem, depends much ana aina gani ya ugonjwa wa moyo as kila ugonjwa merits special and unique consideration. In other words it is not generalizable.
What is generalizable ni kwamba kwa kila mtu mwenye heart problem awe makini linapokuja swala la kungonoka. This comes as kwenye tendo zima brings about excitement and increase work demand on the heart that may comprimise smooth function of the already sick heart and inadvertently cause fatal outcome. Matukio haya siyo mageni katika jamii zetu all over the world.
but just to re-iterate my point, specific heart conditions warrant specific health tips and advice but al together sex is not absolutely contraindicated, however adviced at 'owners' discretion.
