Selecting patients with coronary multivessel disease (MVD) or no stenosis using myocardial perfusion imaging (MPI) is challenging. We aimed to create a model predict MVD combination of quantitative MPI values and background factors patients. also assessed whether in the same database could be selected who do not require rest studies (stress-only imaging). analyzed data from 1001 had been by stress at 12 centers 463 undergone revascularization Japan. Quantitative based on were obtained cardioREPO software, which included defect scores, left ventricular ejection fractions volumes. Factors clinical backgrounds that investigated univariate multivariate analyses. alone without identify candidates for stress-only imaging. summed score (SSS), end-diastolic volume, hypertension predictive MVD. A logistic regression was created an area under receiver operating characteristics curve (AUC) 0.825. To more specifically three-vessel disease, AUC 0.847 when SSS, diabetes, selected.

The renin–angiotensin system (RAS) plays a pivotal role in blood pressure regulation. In some cases, this steering mechanism is affected by various deleterious factors (mainly via the overactivation of RAS) causing cardiovascular damage, including coronary heart disease (CHD) that can ultimately lead to chronic failure (CHF). This not only causes disability and absenteeism from work but also imposes significant healthcare costs globally. incidence diseases has escalated exponentially over years with major outcome form CHD, stroke, CHF. involvement RAS been extensively researched limelight on CHD. may trigger cascade events atherosclerotic mayhem, which CHD related aggravation damaging endothelial lining vessels inflammatory oxidative stress pathways.

Abstract Invasive functional coronary angiography (FCA), an angiography-derived physiological index of the significance obstruction, is a novel assessment tool for obstruction that does not require utilization pressure wire. This technology enables operators to rapidly evaluate relevance stenoses during and even after while reducing burden cost complication risks related FCA can be used treatment decision-making revascularization, strategy planning percutaneous intervention, procedure optimization. Currently, various software-computing FCAs are available worldwide, with unique features in their computation algorithms functions.

Coronary artery disease (CAD) is a common condition caused by the accumulation of atherosclerotic plaques. It can be classified into stable CAD or acute coronary syndrome. computed tomography angiography (CCTA) has high negative predictive value and used as first examination for diagnosing CAD, particularly in patients at intermediate-to-high risk. CCTA also adopted syndrome, low-to-intermediate Myocardial ischemia does not always co-exist with stenosis, positive myocardial limited. However, overcome this limitation recent technological advancements such CT perfusion CT-fractional flow reserve.

Despite guideline-based recommendation of the interchangeable use instantaneous wave-free ratio (iFR) and fractional flow reserve (FFR) to guide revascularization decision-making, iFR/FFR could demonstrate different physiological or clinical outcomes in some specific patient lesion subsets. Therefore, we sought investigate impact difference between iFR FFR-guided decision-making on patients with left main disease (LMD). In this international multicenter registry LMD interrogation, identified 275 whom assessment was performed both iFR/FFR. Major adverse cardiovascular event (MACE) defined as a composite death, non-fatal myocardial infarction, ischemia-driven target revascularization. The receiver-operating characteristic analysis for predict MACE respective deferred performed. 153 deferral, occurred 17.0% patients. optimal cut-off values FFR were 0.88 (specificity:0.74; sensitivity:0.65) 0.76 (specificity:0.81; sensitivity:0.46), respectively. area under curve (AUC) significantly higher than (0.74; 95%CI 0.62-0.85 vs. 0.62; 0.48-0.75; p = 0.012). 122 coronary revascularization, 13.1% 0.92 (specificity:0.93; sensitivity:0.25) 0.81 (specificity:0.047; sensitivity:1.00), AUCs not (0.57; 0.40-0.73 0.46; 0.31-0.61; 0.43).

Abstract Standard modifiable cardiovascular risk factors (SMuRFs), such as hypertension, diabetes, dyslipidemia, and current smoking, are associated with the development of atherosclerotic diseases including acute myocardial infarction (MI). Thus, therapeutic approaches against SMuRFs important primary secondary prevention diseases. In patients MI, however, prognosis is counterintuitively poor when lacking. The growing evidence has explored prevalence, pathophysiology, SMuRF-less in MI suggested potential underlying mechanisms. This review article summarizes clinical relevance lack MI.
