Conclusions: This retrospective registry-based study provides a picture of CIED first implants in HCM patients in a Swedish tertiary university hospital. ICDs were the most commonly implanted devices, covering 59% of CIED implants. HCM patients receiving a pacemaker or an ICD had different epidemiological and clinical profiles.

In this study, we describe spontaneous lesions found in 39 male RccHan:WIST rats used as a control in a carcinogenicity study. Neoplastic lesions were frequently seen in the endocrine system, such as pituitary adenomas in the pars distalis. This strain exhibited a high incidence of thymoma (10.3%), compared to other strains. We encountered an oligodendroglioma, a pituitary adenoma of the pars intermedia, and a prostate adenocarcinoma, which are comparatively rare in rats. While the variety and incidence of non-neoplastic lesions were similar to those in other strains, several interesting lesions occurred with relatively hi...

Conclusion: Patients with HCM may have higher plasma D-dimer levels than subjects without HCM. D-dimer levels in patients with HCM are influenced by age, sex, atrial fibrillation, statin therapy and diastolic blood pressure. PMID: 32057272 [PubMed - as supplied by publisher]

ConclusionsSubstantial recovery of LV function occurs within 12  months in most patients with recent‐onset DCM. Women had the greatest improvement in LVEF. A low LV contractile reserve measured by dobutamine stress CMR appears to identify patients whose LVEF is less likely to recover.

ConclusionsCauses for the observed mortality imbalance associated with revusiran were thoroughly investigated and no clear causative mechanism could be identified. Although the results suggest similar progression of cardiac parameters in both treatment arms, a role for revusiran cannot be excluded.Clinical Trial RegistrationNCT02319005.

Ventricular tachycardia (VT) is a potentially life-threatening heart rhythm disorder based on a reentry circuit within a ventricular substrate which may degenerate into ventricular fibrillation and cardiac arrest. Substrate-related VT can occur due to coronary artery disease or other structural cardiomyopathies, including non-ischemic dilated cardiomyopathy (DCM) [1]. The first-line and only life-saving treatment of hemodynamically unstable VTs without a reversible cause according to current guidelines is the implantation of a implantable cardioverter-defibrillator (ICD) [2].

Conclusions: The development of a pheochromocytoma from an adrenal non functional adenoma is an extremely rare event, but potentially life-threating because of the catecholamine-associated cardiovascular toxicity. In particular, TTS is a form of cardiomyopathy that has been increasingly described as associated with catecholamine-secreting tumors. The exclusion of pheochromocytoma in a patient with TTS has important therapeutic implications, since the administration of β-blockers may be extremely harmful in patients with catecholamine surge in the absence of adequate α-blockage.

Fibrosis is a direct and indirect target of established HF therapies, namely inhibitors of the renin-angiotensin-aldosterone system, but its resilience to therapy warrants a search for novel, more t...
