Type D personality has been consistently associated with adverse cardiovascular health with atypical cardiovascular reactions to psychological stress one potential underlying mechanism. As Type D individuals have been noted to report lower social support and greater perceptions of negativity in social interactions, this study examined if the association between Type D personality and cardiovascular reactivity was mediated by these social relationships. A sample of 195 undergraduate students (138 female) participated in this observational study, where they completed measures assessing Type D personality (DS14), social support, and perceptions of negative social relationships (National Institute of Health social relationship scales), before undergoing a traditional cardiovascular reactivity protocol...

REVIEW
Jenica N Upshaw
Moderate-level evidence suggests that cardiac troponin and natriuretic peptides are useful for risk stratification and early identification of anthracycline cardiotoxicity; however, many of these studies used older chemotherapy regimens, and thus, the applicability to current anthracycline treatment regimens is uncertain. Further research is needed to determine optimal timing and thresholds for troponin and natriuretic peptides in anthracycline-treated patients and evaluate these and other promising biomarkers for anti-HER2 therapies, thoracic radiation, anti-VEGF therapy, and fluoropyrimidine therapy-related cardiotoxicity...

Heart rate variability biofeedback (HRV-BF) has been confirmed to increase heart rate variability (HRV) and cardiac outflows by baroreflex in healthy populations and clinical patients. Autogenic training (AT) is common used in the psychological intervention. This study integrates a single-session of HRV-BF and AT into a high-technology mobile application (app), and examines the effects on HRV indices, breathing rates, and subjective relaxation scores. Healthy college students were recruited and assigned to the single-session HRV-BF group or AT group...

Sympathetic neural remodeling, which involves the inflammatory response, plays an important role in ventricular arrhythmias (VAs) after myocardial infarction (MI). Adrenergic receptors on macrophages potentially modulate the inflammatory response. We hypothesized that the increased level of catecholamines activates macrophages and regulates sympathetic neural remodeling after MI. We treated MI mice with either clodronate or metoprolol for 5 days following coronary artery ligation. Mice without treatment after MI and sham-operation mice served as the positive control and negative control, respectively...
