Left atrial volume (LAV) is an independent prognosticator of cardiovascular events. We investigated whether LAV could be accurately and reliably measured using coronary calcium score (CAC) scan.
Duchenne muscular dystrophy (DMD) is an inherited disease that causes striated muscle weakness. Recently, we showed therapeutic effects of the combination of lisinopril (L), an angiotensin converting enzyme (ACE) inhibitor, and spironolactone (S), an aldosterone antagonist, in mice lacking dystrophin and haploinsufficient for utrophin (utrn+/−;mdx, het mice); both cardiac and skeletal muscle function and histology were improved when these mice were treated early with LS. It was unknown to what extent LS treatment is effective in the most commonly used DMD murine model, the mdx mouse. In addition, current standard-of-care treatment for DMD is limited to corticosteroids. Therefore, potentially useful alternative or additive drugs need to be both compared directly to corticosteroids and tested in presence of corticosteroids. We evaluated the effectiveness of this LS combination in the mdx mouse model both compared with corticosteroid treatment (prednisolone, P) or in combination (LSP). We tested the additional combinatorial treatment containing the angiotensin II receptor blocker losartan (T), which is widely used to halt and treat the developing cardiac dysfunction in DMD patients as an alternative to an ACE inhibitor. Peak myocardial strain rate, assessed by magnetic resonance imaging, showed a negative impact of P, whereas in both diaphragm and extensor digitorum longus (EDL) muscle contractile function was not significantly impaired by P. Histologically, P generally increased cardiac damage, estimated by percentage area infiltrated by IgG as well as by collagen staining. In general, groups that only differed in the presence or absence of P (i.e. mdx vs. P, LS vs. LSP, and TS vs. TSP) demonstrated a significant detrimental impact of P on many assessed parameters, with the most profound impact on cardiac pathology.
Cardiometabolic disease, spanning conditions such as obesity to type 2 diabetes mellitus with excess cardiovascular risk, represents a major public health burden. Advances in preclinical translational science point to potential targets across multiple organ systems for early intervention to improve cardiometabolic health. Validation in clinical trials and translation to care would benefit from in vivo diagnostic techniques that facilitate therapeutic advancements. This review provides a state-of-the-art, multimodality perspective spanning the multiple organ systems that contribute to cardiometabolic disease.
Duchenne muscular dystrophy (DMD), an X-linked disorder affects approximately 1 in 5000 males, is universally associated with heart disease. We previously identified myocardial disease by late gadolinium enhancement (LGE) in DMD subjects at various stages of disease, but the true prevalence is unclear. Cardiovascular magnetic resonance (CMR) is well established for both assessment of ventricular function and myocardial fibrosis by LGE. We sought to establish i) prevalence and distribution of LGE in a large DMD population and ii) relationship among LGE, age, LVEF by CMR and current living status.
Obesity is a strong risk factor for developing endometrial cancer and cardiovascular disease (CVD); consequently, understanding CVD mortality among endometrial cancer survivors is important. We analyzed Surveillance, Epidemiology and End Results Program data for 157,496 endometrial cancer cases diagnosed between 1988 and 2012. We calculated standardized mortality ratios (SMRs) for CVD and all-cause mortality comparing endometrial cancer cases and general population women. We categorized women into one of three prognostic groups (excellent, intermediate and poor) based on tumor characteristics. Cumulative incidence function curves were plotted to visualize absolute mortality risk in the presence of competing risks. Hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated using Cox regression for cause-specific mortality. Deaths were as follows: endometrial cancer 40.6%, CVD 20.5%, other cancers 18.7% and other causes 20.3%. Women with endometrial cancer were more likely to die from CVD (age-adjusted SMR = 8.8, 95% CI = 8.7-9.0) and all causes (age-adjusted SMR = 15.9, 95% CI = 15.8-16.0) compared to general population women. In case-only analyses, higher CVD mortality was associated with older age, Black ethnicity and lack of surgical treatment. Poor prognosis cancers (non-endometrioid histology and late stage) were related to higher mortality from each cause, with the highest HRs observed for endometrial cancer-specific mortality. Among women diagnosed with excellent prognosis tumors (endometrioid, well-differentiated and early stage), absolute risk of CVD mortality surpassed endometrial cancer-specific mortality 5 years after diagnosis. Women diagnosed with common forms of endometrial cancer have a high CVD burden. After diagnosis, cardiovascular health should be emphasized for these women to reduce mortality.
Dressing or preparation of the diabetic foot ulcer is very essential not only to reduce or prevent infection but also for the preparation for definite surgery, if necessary. Present article is about our experience in the evaluation of effectiveness of super oxidized solution in local treatment of diabetic foot ulcers. Out of 20 cases super oxidized solution helped in total healing in 8 cases, and prepared wounds for definite cover by reducing infection and promoting granulations which are pre requisites for definitive surgery in remaining 12 cases.
