Recognition of acute myocardial infarction caused by spontaneous coronary artery dissection of first septal perforator.
Spontaneous coronary artery dissection (SCAD) diagnosis is challenging as angiographic findings are often subtle and differ from coronary atherosclerosis. Herein, we describe characteristics of patients with acute myocardial infarction (MI) caused by first septal perforator (S1) SCAD. ⋯ First septal perforator SCAD events may be overlooked at initial angiography and mis-diagnosed as 'no culprit' MI. First septal perforator SCAD prevalence is likely greater than reported herein and dependent on local expertise and availability of CMR imaging. Spontaneous coronary artery dissection events may occur in intra-myocardial coronary arteries, approaching the resolution limits of invasive coronary angiography.

Mortality risk stratification using artificial intelligence-augmented electrocardiogram in cardiac intensive care unit patients.
An artificial intelligence-augmented electrocardiogram (AI-ECG) algorithm can identify left ventricular systolic dysfunction (LVSD). We sought to determine whether this AI-ECG algorithm could stratify mortality risk in cardiac intensive care unit (CICU) patients, independent of the presence of LVSD by transthoracic echocardiography (TTE). ⋯ The AI-ECG prediction of LVSD is associated with hospital mortality in CICU patients, affording risk stratification in addition to that provided by echocardiographic LVEF. Our results emphasize the prognostic value of electrocardiographic patterns reflecting underlying myocardial disease that are recognized by the AI-ECG.

Association between cardiac rhythm conversion and neurological outcome among cardiac arrest patients with initial shockable rhythm: a nationwide prospective study in Japan.
Initial cardiac rhythm, particularly shockable rhythm, is a key factor in resuscitation for out-of-hospital cardiac arrest (OHCA) patients. The purpose of this study was to clarify the association between cardiac rhythm conversion and neurologic prognosis in OHCA patients with initial shockable rhythm at the scene. ⋯ Findings showed that the 1-month neurologic outcome in OHCA patients who converted to non-shockable rhythm at hospital arrival was very poor compared with patients who had sustained shockable rhythm. Also, patients with conversion to PEA had better neurologic prognosis than conversion to asystole.

Multicenter StudyNational trends in coronary intensive care unit admissions, resource utilization, and outcomes.
Emerging evidence suggests that coronary intensive care units are evolving into intensive care environments with an increasing burden of non-cardiovascular illness, but previous studies have been limited to older populations or single center experiences. ⋯ In a national dataset we observed a changing case-mix among patients admitted to a coronary intensive care unit, though the proportion of patients with a primary cardiac diagnosis remained stable. There was an increase in clinical acuity highlighted by critical care therapies, but in-hospital mortality rates for both primary cardiac and non-cardiac conditions declined across all hospitals. Our findings confirm the changing coronary intensive care unit case-mix and have implications for future coronary intensive care unit training and staffing.

Cardiac complications in patients hospitalised with COVID-19.
To determine the frequency and pattern of cardiac complications in patients hospitalised with coronavirus disease (COVID-19). ⋯ This large study among 3011 hospitalised patients with COVID-19 shows that the incidence of cardiac complications during hospital admission is low, despite a frequent history of cardiovascular disease. Long-term cardiac outcomes and the role of pre-existing cardiovascular disease in COVID-19 outcome warrants further investigation.
