Demographic Trends and Changes in the Pre- and In-Hospital Medical Management of Acute Myocardial Infarction During the First 12 Months of the COVID-19 Pandemic in Mie Prefecture - Report From the Mie ACS Registry.

Even though hospital admissions for acute myocardial infarction (AMI) decreased globally during the COVID-19 pandemic in early 2020, limited information is available on subsequent demographic trends in the number of cases and management of AMI through the first 12 months of the COVID-19 pandemic. We assessed demographic trends, patient characteristics, and AMI outcomes (n=730) during the first 12 months of the COVID-19 pandemic and compared them with corresponding months during the control period (February 2016-January 2020; n=2,742) using data from the Mie ACS Registry. Although a 25.

Mechanisms and prediction of short-term natriuretic effect of sodium-glucose cotransporter 2 inhibitor in heart failure patients coexisting type 2 diabetes mellitus.

The mechanisms of the diuretic effect of sodium-glucose cotransporter 2 (SGLT2) inhibitor and its predictors in heart failure (HF) patients with coexisting type 2 diabetes mellitus (T2DM) remain under investigation. A total of 40 hospitalized HF patients with T2DM (68 ± 13 years old, male gender 63%) were prospectively enrolled and received ipragliflozin at a dose of 50 mg once daily after breakfast for at least 4 consecutive days. They underwent first-morning blood and urine tests, and 24-h urine tests before and after short-term ipragliflozin therapy.

Clinical usefulness of instantaneous wave-free ratio for the evaluation of coronary artery lesion with prior myocardial infarction: A multi-center study.

Background: Fractional flow reserve (FFR) is useful for assessing the functional significance of coronary artery stenosis, even in lesions with prior myocardial infarction (pMI). Instantaneous wave-free ratio (iFR) is a vasodilator-free alternative for the physiological assessment of coronary artery stenosis. In addition, iFR shows good diagnostic agreement with FFR and an iFR-guided revascularization strategy was non-inferior to an FFR-guided revascularization strategy.

Untangling the obesity paradox in patients with acute myocardial infarction after primary percutaneous coronary intervention (detail analysis by age).

Background: Obesity is associated with increased morbidity and mortality. However, obesity paradox has been discussed in some patients with cardiovascular disease.

Objectives: We investigated the mechanisms of the obesity paradox in acute myocardial infarction (AMI) patients.

Narrowing of the QRS complex, elimination of late gadolinium enhancement and remarkable reverse remodeling achieved by optimal medical treatment in non-ischemic dilated cardiomyopathy.

A 67-year-old woman presented with exertional dyspnea. An electrocardiogram showed complete left bundle branch block. Cardiac magnetic resonance imaging revealed left ventricular (LV) dilatation with reduced ejection fraction, no evidence of myocardial ischemia and late gadolinium enhancement (LGE) in the inferior LV wall.

Optical coherence tomography analysis of the stent strut and prediction of resolved strut malapposition at 3 months after 2nd-generation drug-eluting stent implantation.

Our objective was to clarify whether thrombogenic problems with stent struts are resolved at 3 months after 2nd-generation drug-eluting stent implantation. Twenty-one patients with stable angina pectoris having 28 (22 zotarolimus-eluting, 6 everolimus-eluting) stents with optical coherence tomography (OCT)-guided percutaneous coronary intervention (PCI) were evaluated. Stent strut coverage and malapposition were evaluated by OCT immediately after PCI and at 3-month follow-up.
