Coronary Microvascular Dysfunction in Cardiomyopathies: Insights on Clinical and Prognostic Roles.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Coronary microvascular dysfunction (CMD) is a key driver of ischemia and prognosis across several non-ischemic cardiomyopathies. This review summarizes the main tools for diagnosing microvascular dysfunction and available evidence on CMD incidence and the prognostic role in patients with cardiomyopathies. In dilated cardiomyopathy, CMD is associated with reduced myocardial blood flow, greater fibrosis, adverse remodeling, and worse outcomes. In hypertrophic cardiomyopathy, CMD is highly prevalent and multifactorial (arteriolar remodeling, reduced capillary density, extravascular compression, diastolic dysfunction, and/or left ventricular (LV) outflow obstruction), correlating with fibrosis, heart failure, and arrhythmias/sudden death. In Takotsubo syndrome, CMD appears acute and reversible, with microvascular spasms as a predominant mechanism and plausible pathophysiologic basis of the event. In arrhythmogenic right ventricular cardiomyopathy, preliminary data show a blunted hyperemic response and autonomic abnormalities that may impair microvascular vasodilation. In infiltrative and storage diseases (amyloidosis and Anderson-Fabry disease), CMD is often early, preceding hypertrophy/fibrosis, and contributes to symptoms, contractile dysfunction, and adverse outcomes; in sarcoidosis, microvascular inflammation reduces coronary flow reserve (CFR) and is associated with events. Targeted therapies remain limited; optimization of risk factors and drugs that modulate endothelial/metabolic function (statins, angiotensin converting enzyme (ACE) inhibitors, vasodilating β-blockers, calcium channel blockers, sodium glucose cotransporter 2 (SGLT2) inhibitors) yielded variable signals; device-based and nonpharmacologic strategies are under investigation. In conclusion, integrating microcirculatory assessment improves risk stratification and may furnish future therapeutic targets across cardiomyopathies.
