In acute coronary syndrome (ACS) patients, those with MS were more likely to be female, have a history of percutaneous coronary intervention, and have a lower left ventricular ejection fraction and higher Thrombolysis in Myocardial Infarction (TIMI) score. Since the MS has a negative long-term impact on cardiovascular mortality and reinfarction in patients with ACS, it can be used as a marker of cardiovascular mortality in patients with ACS and aggressively targeted.
