Systemic microvascular dysfunction in microvascular and vasospastic angina.

Coronary microvascular dysfunction and/or vasospasm are potential causes of ischaemia in patients with no obstructive coronary artery disease (INOCA). We tested the hypothesis that these patients also have functional abnormalities in peripheral small arteries.

Prevalence and correlates of coronary microvascular dysfunction in heart failure with preserved ejection fraction: PROMIS-HFpEF.

To date, clinical evidence of microvascular dysfunction in patients with heart failure (HF) with preserved ejection fraction (HFpEF) has been limited. We aimed to investigate the prevalence of coronary microvascular dysfunction (CMD) and its association with systemic endothelial dysfunction, HF severity, and myocardial dysfunction in a well defined, multi-centre HFpEF population.

Nailfold avascular score and coronary microvascular dysfunction in systemic sclerosis: A newsworthy association.

We aimed to assess the relationship between nailfold videocapillaroscopy (NVC) abnormalities and coronary flow reserve (CFR), a marker of coronary microvascular dysfunction (CMD) in patients with systemic sclerosis (SSc).

Effect of ACE-inhibition on coronary microvascular function and symptoms in normotensive women with microvascular angina: A randomized placebo-controlled trial.

Studies have suggested a beneficial effect of angiotensin-converting enzyme (ACE) inhibition. To explore whether the ACE inhibitor ramipril has a direct effect on the microvasculature beyond the blood pressure (BP) lowering effect, we investigated whether ramipril improved coronary microvascular function in normotensive women with coronary microvascular dysfunction (CMD).

Protein biomarkers and coronary microvascular dilatation assessed by rubidium-82 PET in women with angina pectoris and no obstructive coronary artery disease.

While a plethora of biomarkers have been shown to be associated with coronary artery disease, studies assessing biomarkers in coronary microvascular dysfunction (CMD) are few. We investigated associations between cardiovascular protein biomarkers and non-endothelium dependent CMD assessed by positron emission tomography (PET).

Effect of Low-Dose Intracoronary Alteplase During Primary Percutaneous Coronary Intervention on Microvascular Obstruction in Patients With Acute Myocardial Infarction: A Randomized Clinical Trial.

Microvascular obstruction commonly affects patients with acute ST-segment elevation myocardial infarction (STEMI) and is associated with adverse outcomes.

Improvement of microvascular endothelial dysfunction induced by exercise and diet is associated with microRNA-126 in obese adolescents.

Microvascular endothelial dysfunction, which is at the early stage of atherosclerosis, precedes macrovascular endothelial dysfunction. The study is aimed to investigate the mechanism underlying the improvement of microvascular endothelial dysfunction by exercise and diet in obese adolescents.

Adipose-derived cells improve left ventricular diastolic function and increase microvascular perfusion in advanced age.

An early manifestation of coronary artery disease in advanced age is the development of microvascular dysfunction leading to deficits in diastolic function. Our lab has previously shown that epicardial treatment with adipose-derived stromal vascular fraction (SVF) preserves microvascular function following coronary ischemia in a young rodent model. Follow-up studies showed intravenous (i.v.) delivery of SVF allows the cells to migrate to the walls of small vessels and reset vasomotor tone. Therefore we test...

Chest pain in the absence of obstructive coronary artery disease: A critical review of current concepts focusing on sex specificity, microcirculatory function, and clinical implications.

Patients presenting with chest pain suggestive of coronary artery disease (CAD) who at coronary arteriography appear to be free of obstructive disease have presented a diagnostic and therapeutic challenge since the 1970's. Studies in female patient populations have suggested that this is predominantly a women's syndrome usually caused by microvascular endothelial dependent and independent dysfunction. A critical review of the literature focusing on studies including both women and men revealed that apart fr...

Coronary microvascular disease and clinical prognosis in deferred lesions: The index of microcirculatory resistance.

While fractional flow reserve (FFR) is a good diagnostic index to assess the myocardial ischemia, coronary flow reserve (CFR) and the index of microcirculatory resistance (IMR) can be used to address microvascular status without any significant epicardial disease. The independent predictors of for FFR and IMR are totally different and acts differently on the macro- and micro-vascular dysfunction. In high FFR patients, low CFR and high IMR which indicates the presence of overt microvascular disease demonstra...

Effect of hemorheological parameters on myocardial injury after primary or elective percutaneous coronary intervention.

Abnormal blood viscosity favors atherosclerosis owing to endothelial dysfunction and changes in shear stress. Its effect on coronary microvasculature during percutaneous coronary intervention (PCI) is still unknown. We aimed to investigate the role of hemorheological parameters in the incidence of microvascular obstruction (MVO) and the periprocedural necrosis after primary or elective PCI, and secondarily, we evaluated their prognostic significance.

Lipoprotein Apheresis Acutely Reverses Coronary Microvascular Dysfunction in Patients With Severe Hypercholesterolemia.

The study evaluated whether lipoprotein apheresis produces immediate changes in resting perfusion in subjects with severe hypercholesterolemia, and whether there is a difference in the response between peripheral and coronary microcirculations.

Treg cells depletion is a mechanism that drives microvascular dysfunction in mice with established hypertension.

Microvascular dysfunction is a major complication in hypertensive patients. We previously reported that CD4CD25 T regulatory cells (Treg) play an important preventive role in hypertension-induced vascular dysfunction. However, whether Treg cells therapy and autophagy inhibition could rescue Treg cells survival and microvascular function in established hypertension is an important question that remained unanswered.

Sphingosine-1-Phosphate Reduces Hemorrhagic Shock and Resuscitation-Induced Microvascular Leakage by Protecting Endothelial Mitochondrial Integrity.

Excessive microvascular permeability is a serious complication following hemorrhagic shock and resuscitation (HSR). S1P has been shown to ameliorate microvascular leakage in a model of combined alcohol intoxication and hemorrhagic shock and resuscitation (HSR). In the current study, we tested the hypothesis that S1P reduces HSR-induced microvascular leakage by preserving endothelial cell junctional structure and the endothelial glycocalyx through protection of mitochondrial function. We used an established ...

Why do we care about coronary microvascular dysfunction and heart failure with preserved ejection fraction: addressing knowledge gaps for evidence-based guidelines.

Microvascular dysfunction determines infarct characteristics in patients with reperfused ST-segment elevation myocardial infarction: The MICROcirculation in Acute Myocardial Infarction (MICRO-AMI) study.

In patients with reperfused ST-elevation myocardial infarction (STEMI) both invasive and non-invasive assessments of microvascular dysfunction, the index of microcirculatory resistance (IMR), and microvascular obstruction (MVO) by cardiovascular magnetic resonance (CMR), independently predict poor long-term outcomes.

Assessing coronary plaques: non-invasive and intracoronary imaging and haemodynamic measurements.

Impact of serum lipoprotein(a) on endothelium-dependent coronary vasomotor response assessed by intracoronary acetylcholine provocation.

Lipoprotein(a) [Lp(a)] is an independent risk factor for atherosclerotic vascular disease. However, there are limited data regarding the impact of Lp(a) levels on the incidence and severity of endothelium-dependent coronary vasomotor response.

Relationship between FFR, CFR and coronary microvascular resistance - Practical implications for FFR-guided percutaneous coronary intervention.

The aim was threefold: 1) expound the independent physiological parameters that drive FFR, 2) elucidate contradictory conclusions between fractional flow reserve (FFR) and coronary flow reserve (CFR), and 3) highlight the need of both FFR and CFR in clinical decision making. Simple explicit theoretical models were supported by coronary data analyzed retrospectively.

A pilot clinical study of adjunctive therapy with selective intracoronary hypothermia in patients with ST-segment elevation myocardial infarction.

We aimed to assess the effect of selective intracoronary hypothermia on outcomes in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PPCI).

Early detection of microvascular dysfunction in hypertension: the holy grail of cardiovascular prevention and risk assessment?

Effects of a cluster-randomized school-based prevention program on physical activity and microvascular function (JuvenTUM 3).

It is unknown whether a school-based prevention program has the potential to improve microvascular health in children. This study investigates the impact of the school-based lifestyle intervention program JuvenTUM 3 on physical activity, physical fitness, serum biomarkers and microvascular function.

Association between mild thyroid dysfunction and clinical outcome in acute coronary syndrome undergoing percutaneous coronary intervention.

Thyroid hormones profoundly influence the cardiovascular system, but the effects of mild thyroid dysfunction on the clinical outcome of acute coronary syndrome (ACS) patients undergoing percutaneous coronary intervention (PCI) are not well defined. This study aimed to determine the effect of mild thyroid dysfunction on 12-month prognosis in ACS patients undergoing PCI.

Evaluation of intracoronary hyperoxemic oxygen therapy in acute anterior myocardial infarction: The IC-HOT study.

In the randomized AMIHOT-II trial, supersaturated oxygen [SSO ] delivered into the left anterior descending (LAD) artery via an indwelling intracoronary infusion catheter following primary percutaneous coronary intervention (PCI) significantly reduced infarct size in patients with anterior ST-segment elevation myocardial infarction (STEMI) but resulted in a numerically higher incidence of safety events.

Vascular calcification and not arrhythmia in idiopathic atrial fibrillation associates with sex differences in diabetic microvascular injury miRNA profiles.

Background Atrial fibrillation (AF) in patients without concomitant cardiovascular pathophysiological disease, is called idiopathic atrial fibrillation (iAF). Nonetheless, iAF patients have oftentimes subclinical coronary (micro)vascular dysfunction and, particularly in women, a higher prevalence of subsequent cardiovascular comorbidities. Previously, we identified a plasma miRNA association with diabetes and microvascular injury in diabetic nephropathy (DN) patients. Therefore, in this study we assessed wh...
