Implementation of Microcirculation Examination in Clinical Practice-Insights from the Nationwide POL-MKW Registry.

The assessment of coronary microcirculation may facilitate risk stratification and treatment adjustment. The aim of this study was to evaluate patients' clinical presentation and treatment following coronary microcirculation assessment, as well as factors associated with an abnormal coronary flow reserve (CFR) and index of microcirculatory resistance (IMR) values. This retrospective analysis included 223 patients gathered from the national registry of invasive coronary microvascular testing collected between 2018 and 2023.

A head-to-head comparison of wall motion score index, force, strain, and ejection fraction for the prediction of SYNTAX and Gensini coronary scores by dobutamine stress echocardiography.

Background: Predicting the severity of coronary artery disease (CAD) may be possible during dobutamine stress echocardiography (DSE) with various indices of left ventricular function.

Aims: We assessed the relative value of ejection fraction (EF), force, global longitudinal strain (GLS), and wall motion score index (WMSI) in predicting SYNTAX and Gensini scores in patients with known or suspected CAD.

Methods: We prospectively enrolled 223 patients (120 men; mean [SD] age, 62 [9] years) and assessed the following indices: 1) EF (with triplane imaging); 2) force, calculated as the ratio of systolic blood pressure to left ventricular end‑systolic volume; 3) GLS; 4) WMSI.

Takotsubo cardiomyopathy in the case of 72-year-old teacher after work-related psychological stress. Evolution of left ventricular longitudinal strain - Delayed but complete recovery in automated function imaging (AFI).

Takotsubo cardiomyopathy (TC) is related to a transient systolic dysfunction of left ventricle (LV), accompanied by clinical and electrocardiographic symptoms of myocardial ischemia in the absence of hemodynamically significant coronary artery disease. Takotsubo cardiomyopathy is usually provoked by a psychologically or/and physically stressful event which may be related to occupational activities. Although visually assessed evolution of LV function is well documented, the data concerning strain changes is sparse and various patterns of deformation abnormalities are suggested.
