Different Microcirculation Response Between Culprit and Non-Culprit Vessels in Patients With Acute Coronary Syndrome.

ABSTRACT: Background This study investigated whether the microvascular dysfunction differed between culprit and non-culprit vessels in patients with acute coronary syndrome who underwent percutaneous coronary intervention. Methods and Results In 115 prospectively recruited patients, after successful percutaneous coronary intervention, culprit and non-culprit intracoronary hemodynamic measurements were performed and repeated at 6-month follow-up. ¹³N-ammonia positron emission tomography was performed at 6-month follow-up visit to determine absolute myocardial blood flow. The resistance values of each vessel were calculated using the coronary pressure data and the myocardial blood flow values obtained from ¹³N-ammonia positron emission tomography data. We compared the measurement
