Prognostic Implications of Resistive Reserve Ratio in Patients With Coronary Artery Disease

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2020
Background Resistive reserve ratio is a thermodilution‐based index which integrates both coronary flow and pressure. Resistive reserve ratio represents the vasodilatory capacity of interrogated vessels including both epicardial coronary artery and ...

Intravascular Imaging versus Physiological Assessment versus Biomechanics—Which Is a Better Guide for Coronary Revascularization

Diagnostics, 2023
Today, coronary artery disease (CAD) continues to be a prominent cause of death worldwide. A reliable assessment of coronary stenosis represents a prerequisite for the appropriate management of CAD.

Coronary flow reserve and microcirculatory resistance in patients with coronary tortuosity and without atherosclerosis

Journal of International Medical Research, 2020
Objective Coronary tortuosity may affect epicardial coronary arterial blood flow. This study aimed to investigate the effect of coronary tortuosity on coronary flow reserve and the coronary microcirculation in patients without apparent coronary ...

Reduced coronary flow reserve in Anderson-Fabry disease measured by transthoracic Doppler echocardiography

Cardiovascular Ultrasound, 2005
Coronary flow reserve was assessed in a patient with Anderson-Fabry disease complicated by symmetric left ventricular hypertrophy. Coronary flow reserve was measurable in all three major coronary arteries providing an opportunity to compare regional ...

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

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2020
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.

What is the Role of Coronary Physiology in the Management of Patients with Chronic Coronary Syndromes?

Reviews in Cardiovascular Medicine, 2022
The use of coronary physiology in patients with chronic coronary syndromes is highly variable, and the evidence base complex. Tests of coronary physiology have traditionally been invasive (e.g., fractional flow reserve), but novel non-invasive methods ...

Effects of Intracoronary Alteplase on Microvascular Function in Acute Myocardial Infarction

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2020
Background Impaired microcirculatory reperfusion worsens prognosis following acute ST‐segment–elevation myocardial infarction. In the T‐TIME (A Trial of Low‐Dose Adjunctive Alteplase During Primary PCI) trial, microvascular obstruction on cardiovascular ...
