Literature reports the potential effects that cannabis can have in cardiovascular complications.

Acute myocardial infarction (AMI) is more commonly known as a heart attack, which can lead to heart failure. In a multivariable analysis, it revealed that marijuana use can lead to an increased risk in AMI development, however, THC and CBD may have opposing effects. THC decreases in contractile force and coronary flow, while also inducing an increased frequency. On the other hand, CBD can increase contractile force and coronary flow, but it does not change the heart rate.

Investigations about mortality post AMI and medical cannabis

Moreover, a new study in 2018 was carried out on the relationship between patients who suffered a heart attack from 1994 – 2013 and the use of cannabis. The results showed a reduced mortality post AMI. An explanation to this can be a hint on the possible cardiac infarct preventative effects in cannabis. Although cannabis has this positive effect, consumers can still have an increased risk of mechanical ventilation after a heart attack.

Therefore, the results show clear evidence that cannabis is not associated with an increased risk, as opposed to the assumptions that it can cause unfavourable effects after a heart attack.
