Prevalence and prognostic impact of nonischemic late gadolinium enhancement in stress cardiac magnetic resonance
Conclusion NI-LGE can be detected in 11% of patients during stress-CMR providing a diagnosis of nonischemic cardiac disease. Patients with NI-LGE have worse prognosis than those with no-LGE.

Main determinants of physician-driven amiodarone discontinuation in clinical practice
ConclusionStudy showed that within the first two years of treatment, despite persistent indication, amiodarone was discontinued in 1 out of 10 patients in the absence of side effects, mostly in younger patients with less comorbidities, which may not always be justified. There is a need for qualitative research to elucidate the reasons for such physicians ’ decisions.

Functional Calsequestrin-1 Is Expressed in the Heart and Its Deficiency Is Causally Related to Malignant Hyperthermia-Like Arrhythmia
Conclusions: Casq1 is expressed in the heart, where it regulates SR Ca2+ release and heart rate. Casq1 deficiency independently causes MH/EHS-like ventricular arrhythmia by trigger-induced Casq1 oligomerization and a relief of its inhibitory effect on RyR2-mediated Ca2+ release, thus revealing a new inherited arrhythmia and a novel mechanism for MH/EHS arrhythmogenesis.PMID:34162222 | DOI:10.1161/CIRCULATIONAHA.121.053255

Impact of left ventricular ejection fraction and preoperative hemoglobin level on perioperative adverse cardiovascular events in noncardiac surgery
AbstractThe prediction of a perioperative adverse cardiovascular event (PACE) is an important clinical issue in the medical management of patients undergoing noncardiac surgery. Although several predictors have been reported, simpler and more practical predictors of PACE have been needed. The aim of this study was to investigate the predictors of PACE in noncardiac surgery. We retrospectively analyzed 723 patients who were scheduled for elective noncardiac surgery and underwent preoperative examinations including 12-lead electrocardiography, transthoracic echocardiography, and blood test. PACE was defined as cardiac death,...

Clinical significance of new ‐onset atrial fibrillation in patients with hypertrophic cardiomyopathy
ConclusionsIn our HCM registry in an aged Japanese community, a significant proportion developed AF. The presence of AF, particularly new-onset AF, was associated with increased incidence of HCM-related events. AF may not be just a marker of disease stage but an important trigger of adverse events.
