Can a drug overdose lead to death by Hypertrophic Cardiomyopathy or is this condition always genetic.?

If the condition is always genetic can it be aggravated by drug abuse which may in turn lead to sudden heart failure?

Hypertrophic cardiomyopathy (HCM) is quite a heterogeneous condition. What I mean by that is that HCM may present quite differently between individuals, even within the same family.

In general, the risk of sudden cardiac death is assessed on the basis of a family history, a personal history of collapses and from echocardiographic features. Sometimes genetic testing is included in this assessment.

HCM is caused by mutations in sarcomeric proteins (the proteins which make up the contractile apparatus of the heart muscle). However, it is possibly to develop a form of hypertrophied heart which is not linked to this genetic abnormality. This may result from lots of exercise (mostly at competitive level) and occasionally for abuse of drugs including cocaine and amphetamines. But strictly speaking this type of hypertrophy is different from HCM both in its origins and outcome.

Yes, taking drugs (especially cocaine or amphetamines) may increase the likelihood of developing a serious heart rhythm abnormality which could lead to death. Obviously the greater the underlying background risk (from the HCM), the greater the chances that these drugs could cause problems.

So bottom line is....if you, or someone you know, has HCM, then drugs should be avoided, particularly those which may be pro-arrhythmogenic.

I think its always genetic, but drugs certainly won't help it any.

Since the heart muscle is already compromised, whether genetic or not, any type of drug ( s) that affect the heart muscle will only make the pre-existing condition worse. Especially, if the drugs can alter ( change) the heart rate and/or rhythm. So, yes, certain drugs can trigger a heart that is all ready in a state that is outside the norm ( normal ). Actually, it would probably be a good idea to avoid caffeine, chocolate as these are heart stimulants. I hope that this helps.
