Influence of percutaneous coronary intervention on coronary microvascular resistance index.
BACKGROUND Coronary microvascular resistance during maximal hyperemia is generally assumed to be unaffected by percutaneous coronary interventions (PCIs). We assessed a velocity-based index of hyperemic microvascular resistance (h-MR(v)) by using prototypes of a novel, dual-sensor (Doppler velocity and pressure)-equipped guidewire before and after PCI to test this hypothesis. METHODS AND RESU...
متن کاملEffect of Elective Percutaneous Coronary Intervention on Hyperemic Absolute Coronary Blood Flow Volume and Microvascular Resistance.
BACKGROUND The hemodynamics involved in the relationship between absolute coronary blood flow (ABF) volume and myocardial resistance (MR) are complex, and the effect of percutaneous coronary intervention (PCI) on their changes remains unclear. The aim of this study was to investigate the differences in hyperemic ABF and MR before and after elective PCI using a thermodilution method. METHODS A...
متن کاملClopidogrel Resistance and its Impact on Clinical Outcome of Iranian Patients Undergoing Percutaneous Coronary Intervention
The aim of current study was evaluating the frequency of clopidogrel resistance and its impact on clinical outcome of patients in Iranian patients. Patients undergoing percutaneous coronary intervention in Imam Hussein Medical center, Tehran, Iran, who received standard dosage of clopidogrel (Plavix®, Sanofi, France, 600 mg loading dose and 75 mg/day afterward) were recruited. Platelet aggregat...

متن کاملCurrent practice of percutaneous coronary intervention on patients with acute coronary syndrome in Iran: A prospective observational study
Background: Frequent Percutaneous Coronary Intervention (PCI) procedures are being performed on a daily basis in Iran. However, no study has been reported on the current PCI practice in patients with acute coronary syndrome (ACS) in Iran. We aimed to describe the clinical characteristics and treatment patterns in Iranian ACS patients treated with PCI. Methods: Between February 2017 and July...
