Coronary Microvascular Angina: A State-of-the-Art Review

open access: yesFrontiers in Cardiovascular Medicine, 2022
Up to 60–70% of patients, undergoing invasive coronary angiography due to angina and demonstrable myocardial ischemia with provocative tests, do not have any obstructive coronary disease. Coronary microvascular angina due to a dysfunction of the coronary

Coronary Microcirculation and the No-reflow Phenomenon

open access: yesCurrent Pharmaceutical Design, 2018
The no-reflow phenomenon refers to the post-percutaneous coronary intervention condition in which, despite re-establishing epicardial coronary vessel patency, the flow to the previously ischemic myocardium is markedly reduced. When it does occur, it attenuates the beneficial effect of reperfusion therapy and substantial regions of the myocardium fail

Diseases of the coronary microcirculation: diagnosis and treatment

open access: yesDeutsches Ärzteblatt international, 2023
Coronary microvascular dysfunction (CMD) comprises a variety of pathogenic mechanisms that impair the microcirculation of the heart. Clinical studies have shown that 30-50% of patients suffering from myocardial ischemia without significant coronary artery stenosis have CMD.

Ultrasound‐Triggered piRNA Delivery Using Biomimetic Phase‐Changeable Nanoparticles for Theranostics of Myocardial Infarction

open access: yesAdvanced Science, EarlyView.
A biomimetic ultrasound‐responsive piRNA delivery nanoparticle platform (piR‐NPs) enables targeted delivery and ultrasound (US)‐triggered release of piR‐1873 in infarcted myocardium. The released piR‐1873 suppresses Usp2‐mediated RIP1/RIP3/MLKL necroptosis, reduces myocardial injury and fibrosis, and promotes cardiac functional recovery, providing a ...

Evaluation of the coronary flow by the coronary clearance time in patients with cardiac syndrome X

open access: yesJournal of International Medical Research, 2018
Objective The vessels involved in the microcirculation are too small to be visualized by conventional angiography and no tools are currently available that can directly evaluate the coronary microcirculation.

New Targets in Heart Failure Drug Therapy

open access: yesFrontiers in Cardiovascular Medicine, 2021
Despite recent advances in chronic heart failure management (either pharmacological or non-pharmacological), the prognosis of heart failure (HF) patients remains poor.

Stroke‐Heart Syndrome: Mechanisms, Temporal Phenotypes, and Diagnostic Reasoning

open access: yesAdvanced Science, EarlyView.
Stroke‐heart syndrome describes new or worsened cardiac abnormalities after acute stroke. This Review defines its clinical boundaries, traces autonomic, inflammatory, endothelial, and supply‐demand mechanisms across time, and proposes provisional phenotypes that integrate lesion location, premorbid cardiac substrate, serial biomarkers ...

Acute effects of chewing tobacco on coronary microcirculation and hemodynamics in habitual tobacco chewers

open access: yesJournal of the Practice of Cardiovascular Sciences, 2015
Background: Long-term adverse cardiovascular effects of smokeless tobacco are well established, however, the effect of chewing tobacco on coronary microcirculation and hemodynamic have not been studied.

Interventional therapies for chronic heart failure: An overview of recent developments

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1081-1094, April 2025.
Abstract Heart failure (HF), the final manifestation of most cardiovascular diseases, has become a major global health concern, affecting millions of individuals. Despite basic drug treatments, patients present with high morbidity and mortality rates. However, recent advancements in interventional therapy have shown promising results in improving the ...

Connecting the dots: A narrative review of the relationship between heart failure and cognitive impairment

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1119-1131, April 2025.
Abstract Large clinical data underscore that heart failure is independently associated to an increased risk of negative cognitive outcome and dementia. Emerging evidence suggests that cerebral hypoperfusion, stemming from reduced cardiac output and vascular pathology, may contribute to the largely overlapping vascular dementia and Alzheimer's disease ...
