Does melatonin reduce blood clotting and heart strain in people with heart disease?

Melatonin administration is associated with reduced platelet aggregation and lower serum catecholamine levels in patients with cardiovascular conditions. These hemodynamic and hematological changes are proposed to contribute to decreased thrombotic risk and reduced cardiac workload, forming part of melatonin's broader cytoprotective profile in ischemic and hypertensive states.
