Alcohol septal ablation in patients aged 75 years or older with hypertrophic obstructive cardiomyopathy.

Objective: Outcome data for patients ≥75 years with hypertrophic obstructive cardiomyopathy (HOCM) undergoing alcohol septal ablation (ASA) are lacking. Therefore, a retrospective single-centre analysis was conducted.

Methods: The data of all consecutive ASAs, that were performed at our institution between 1 September 1997 and 31 July 2021 in patients with HOCM with left ventricular outflow tract gradients (LVOTG) ≥50 mm Hg, were collected from patient reports.

Cannabis-induced recurrent myocardial infarction in a 21-year-old man: a case report.

Background: Acute coronary syndrome (ACS) is rarely caused by coronary artery disease in young patients unless cardiovascular risk factors are present. Although non-atherosclerotic causes of ACS are rare, they need to be considered in young patients.

Case Summary: We report on a 21-year-old patient referred to our institution with ACS.

Dopamine receptor subtypes in the human coronary vessels of healthy subjects.

Objective: Dopamine D(1)-D(5) receptors subtypes were studied in human coronary vessels of healthy subjects to assess their localization and their expression.

Methods: Samples of intraparenchymal and extraparenchymal branches of human coronary arteries and veins were harvested from four normal native hearts explanted from four young brain dead heart donors in case of orthoptic transplant, not carried out for technical reasons. In all the samples morphological, biochemical, immunochemical, and morphometrical studies were performed including quantitative analysis of images and evaluation of data.

A study on QT interval in patients affected with inflammatory bowel disease without cardiac involvement.

Cardiac involvement has been studied quite extensively in patients affected by inflammatory bowel disease but, as of now, there is no data regarding QT alterations which are well known to be linked to the risk of dangerous arrhythmias. In this study, QT parameters were digitally measured on standard 12-lead ECG in a population of 20 patients affected by inflammatory bowel disease (IBD), with no prior (recent or old) history of cardiac disease and no evidence of electrolyte imbalance. Eighteen healthy subjects formed the control group.
