Multicenter Study Comparative Study
All-cause readmission and repeat revascularization after percutaneous coronary intervention.
Percutaneous coronary intervention (PCI) is one of the most frequently performed cardiac interventions. However, there is limited data regarding the cause of recurrent hospitalization and repeat revascularization. The aim of this study was to assess re-hospitalization and repeat revascularization within 30 days of the initial hospitalization for PCI, using data from Opolskie Voivodeship, National Health Fund (NHF) Registry. ⋯ Almost one in seven PCI patients requires readmission within 30 days of hospital discharge. Approximately 50% of all readmitted PCI patients resulted in a repeat revascularization procedure. PCI patients who were readmitted within 30 days of an index PCI procedure had a significantly higher all-cause 30-day mortality rate.

The heart was very sensitive to fluctuating thyroid hormone levels. To assess intra-left ventricular (LV) systolic asynchrony in patients with subclinical thyroid dysfunction. ⋯ Patients with subclinical hypothyroidism present evidence of LV asynchrony by TSI. LV systolic asynchrony could be a warning sign of the early stage in cardiac systolic dysfunction in subclinical hypothyroid patients.

The interval from the pacemaker stimulus to the onset of the earliest paced QRS complex (latency) may be prolonged during left ventricular (LV) pacing. Marked latency is more common with LV than right ventricular (RV) pacing because of indirect stimulation through a coronary vein and higher incidence of LV pathology including scars. During simultaneous biventricular (BiV) pacing a prolonged latency interval may give rise to an ECG dominated by the pattern of RV pacing with a left bundle branch block configuration and commonly a QS complex in lead V1. ⋯ During LV only pacing (RV channel turned off) RV anodal pacing may also occur in a more obvious form so that the ECG looks precisely like that during BiV pacing. RV anodal stimulation may complicate threshold testing and ECG interpretation and should not be misinterpreted as pacemaker malfunction. Programming the V-V interval (LV before RV) in the setting of RV anodal stimulation cancels the V-V timing to zero.

Our study set out to determine the prevalence of depressive symptoms and variables that influence its presence in patients hospitalized for heart failure. Depression is associated with a substantially increased risk of developing heart failure in individuals at risk, and has been related to adverse outcomes in patients with established heart failure. It is important to determine its prevalence in different populations and assess related causes. ⋯ Because depressive symptoms in patients hospitalized for heart failure are very common, it is important to detect these disorders. The prevalence of these varies according to socio-demographic and clinical data, and these factors should be taken into consideration when planning future studies, as well as screening and intervention programs for co-morbid depressive disorders in hospitalized patients with heart failure.

Case Reports
Acute myocarditis mimicking acute myocardial infarction associated with pandemic 2009 (H1N1) influenza A virus.
The prevalence of myocardial involvement in influenza infection ranges from 0% to 11% depending on the diagnostic criteria used to define myocarditis. Whether such an association holds for the novel influenza A strain, pandemic-2009-H1N1, remains unknown. ⋯ Although history, physical examination, laboratory data points, and electrocardiogram are helpful in distinguishing myocarditis from myocardial infarction, differential diagnosis can sometimes be difficult. Here, we present the first known report of acute myocarditis mimicking acute myocardial infarction associated with the pandemic influenza A virus (H1N1) infection.
