levodopa

Levodopa is the most effective medical treatment for Parkinson’s disease (PD) to date. As dopamine is known to increase cardiac inotropism and vasomotor tone, peripheral dopamine decarboxylase inhibitor is coadministered to suppress the peripheral conversion of levodopa to dopamine. Levodopa poses potential cardiovascular risks, thus its use in patients with existing coronary artery disease needs to be carefully monitored. We report a case of an elderly male with newly diagnosed PD who developed non-ST-elevation myocardial infarction following levodopa (Madopar) initiation.
