Link of renal microcirculatory dysfunction to increased coronary microcirculatory resistance in hypertensive patients [PDF]

Cardiology Journal, 2017
This study investigated the correlation between renal microcirculation and coronary microcirculation in hypertensive patients.Participants consisted of 231 consecutive candidates who were referred to the Second Affiliated Hospital of Wenzhou Medical University from March 2014 to May 2016 for elective coronary angiography due to suspected myocardial ...

Coronary Microcirculatory Resistance Is Independent of Epicardial Stenosis [PDF]

Circulation: Cardiovascular Interventions, 2012
Background— Recent studies show that coronary microcirculatory impairment is an independent predictor of poor outcomes in patients with cardiovascular disease. However, controversy exists over whether microcirculatory resistance, a measure of coronary microcirculatory status, is dependent on epicardial stenosis severity ...

The Potential Use of the Index of Microcirculatory Resistance to Guide Stratification of Patients for Adjunctive Therapy in Acute Myocardial Infarction

JACC: Cardiovascular Interventions, 2019
The goal of reperfusion therapies in ST-segment elevation myocardial infarction has evolved to include effective reperfusion of the microcirculation subtended by the culprit epicardial coronary artery. The index of microcirculatory resistance is measured

Invasive minimal Microvascular Resistance Is a New Index to Assess Microcirculatory Function Independent of Obstructive Coronary Artery Disease [PDF]

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2016
Background Coronary microcirculatory dysfunction portends a poor cardiovascular outcome. Invasive assessment of microcirculatory dysfunction by coronary flow reserve (CFR) and hyperemic microvascular resistance (HMR) is affected by coronary artery ...

Coronary Flow Reserve and Microcirculatory Resistance in Patients With Intermediate Coronary Stenosis

Journal of the American College of Cardiology, 2016
The prognostic impact of microvascular status in patients with high fractional flow reserve (FFR) is not clear.The goal of this study was to investigate the implications of coronary flow reserve (CFR) and the index of microcirculatory resistance (IMR) in patients who underwent FFR measurement.Patients with high FFR (>0.80) were grouped according to CFR

Influence of the amount of myocardium subtended to a coronary stenosis on the index of microcirculatory resistance. Implications for the invasive assessment of microcirculatory function in ischaemic heart disease

EuroIntervention, 2017
The index of microcirculatory resistance (IMR) is increasingly used to quantify microcirculatory function. However, in normal coronary arteries, resistance increases with the branching structure of the coronary tree, which suggests that IMR could be influenced by the amount of downstream myocardial mass (MM).
