Worse, these problems may occur even in people whose cocaine exposure is limited to occasional, recreational usage.
Cardiac Effects of Cocaine
Cocaine is a drug that inhibits the reuptake ofnorepinephrinein neurons throughout the body.
The exaggerated sympathetic nervous activity has profound effects on the cardiovascular system.

It does this by causing constriction of the capillaries, thus reducing the blood flow to the heart muscle.
The cardiovascular system thus becomes extremely stressed.
Most cocaine-induced heart attacks occur within a few hours of using the drug.
While there are many causes of aortic dissection, in young people cocaine use is a prevalent cause.
Coronary Artery Aneurysm
Coronary artery aneurysms are balloon-like dilations of coronary arteries.
Myocarditis and Cardiomyopathy
Cocaine causesmyocarditis, which is inflammation of the heart muscle.
Myocarditis can lead to damage of the heart muscle (cardiomyopathy).
As a result,heart failuremay occur.
However, cocaine use complicates therapy in a few important ways.
Beta-Blockers
Beta-blockers should not be used in patients currently under the influence of cocaine.
This takes a critical treatment tool out of the doctors hands when they are dealing with a heart attack.
