Clinical Trial Summary

To compare the effect of a single high dose of atorvastatin versus rosuvastatin preloading on microvascular coronary perfusion as determined by CTFC in patients with ST-segment elevation myocardial infarction (STEMI) undergoing PCI.

Description:

Acute myocardial infarction (MI) indicates irreversible myocardial injury resulting in necrosis of a significant portion of myocardium which is caused mostly by coronary plaque rupture or erosion. It could result in several clinical complications and impact cardiac prognosis .

Worldwide, ischemic heart disease is the single most common cause of death and its frequency is increasing, now Accounts for almost 1.8 million annual deaths.

Cholesterol reduction with HMG-CoA (3-hydroxy-3-methylglutaryl coenzyme A) reductase inhibitors or statins has been shown to improve mortality and cardiovascular morbidity in patients with established coronary artery disease (CAD).

Previous evidence suggests that statins have various favorable effects on vascular system that are not directly related to their impact on lipid metabolism. Beyond lowering lipids, statins have favorable effects on platelet adhesion, thrombosis, endothelial function, plaque stability, and inflammation. . As with ACS, the vascular injury from coronary angioplasty and stent placement induces platelet activation, thrombosis, and inflammation within the vessel wall and the distal microvasculature. Therefore, in addition to a long-term benefit associated with lipid lowering, statin therapy might play a beneficial role early after PCI.

Conventional TIMI flow grading (Thrombolysis In Myocardial Infarction) is a predictor of cardiac outcome after acute myocardial infarction and PCI, but it has several limitations.

The CTFC (corrected TIMI frame count) another approach to grade flow impairment, is an objective, quantitative, reproducible, and sensitive index for coronary blood flow[9].

TIMI flow may appear normal visually, but may correlate to abnormal CTFC. The CTFC has been proposed to have incremental prognostic accuracy in predicting survival outcome with reperfusion therapy . Higher CTFC values after PCI have also been found to be associated with poor clinical outcomes.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	angiographic parameters	CTFC (corrected TIMI frame count) In the CTFC method, the number of frames required for dye to reach a standardized distal landmark is counted. A correction factor is required to compensate for the longer length of the left anterior descending artery (LAD) compared with the circumflex and right coronary arteries (the number of frames required for dye to traverse the LAD is divided by 1.7). The frame count number after adjustment for vessel length is given the term 'corrected TIMI frame count'.	3 months
Primary	STR (ST-segment resolution) (STR)	ST-segment resolution (STR) was calculated as the sum of ST-segment elevation on initial ECG minus the sum of ST-segment elevation on the ECG at 90 min after PCI, divided by the sum of ST- segment elevation on initial ECG, and was expressed as a percentage . The complete early STR was defined as more than or equal to 70% STR.	3 months
