Left ventricular systolic function assessment in secondary mitral regurgitation: left ventricular ejection fraction vs. speckle tracking global longitudinal strain

Aims Left ventricular (LV) ejection fraction (LVEF) is currently considered for the decision making of patients with mitral regurgitation (MR). However, LVEF represents change in LV volume between end-diastole and end-systole but does not characterize the intrinsic function of the myocardium. In contrast, speckle-tracking global longitudinal strain (GLS) characterizes myocardial deformation. The present study evaluated whether LV GLS may detect further impairment in LV systolic function in dilated cardiomyopathy patients with and without severe secondary MR matched based on LVEF. Methods and results Patients with non-ischaemic dilated cardiomyopathy (N = 150, 59 ± 12 years old, 58% male) were included: 75 patients with severe secondary MR and 75 patients with none or less than mild MR matched 1 : 1 according to LVEF. The LV systolic function was evaluated by LVEF (following Simpson's biplane method), forward ejection fraction (forward stroke volume relative to LV end-diastolic volume), and speckle-tracking GLS. By definition, LVEF was comparable between the two groups (patients with severe MR 31 ± 10 vs. patients with no/mild MR 31 ± 10%, P = 0.93). However, patients with severe MR had significantly lower forward ejection fraction (29 ± 14 vs. 40 ± 18%, P

We examined frequency, clinical characteristics and AF‐related management and outcomes amongst this patient population.MethodsWe retrospectively studied consecutive probands with inherited cardiomyopathy (n=962) and inherited arrhythmia syndromes (n=195) evaluated between 2002 ‐2018.ResultsAF was observed in 5 ‐31% of patients, with the highest frequency in HCM. Age of AF onset was 45.8 ± 21.9 years in the inherited arrhythmia syndromes compared to 53.3 ± 15.3 years in the inherited cardiomyopathies, with 4 CPVT patients developing AF at median age of 20 years. Overall, 11% of patients with AF had a t r...

In conclusion, AF seems to have a higher prevalence in the general population than previously thought, and is mostly associa ted with hypertension, cardiomyopathy and rheumatic heart disease in SSA. It is associated with a high incidence of heart failure and stroke. The management of AF is suboptimal in SSA, especially with a low uptake of oral anticoagulation.This article is protected by copyright. All rights reserved.

CONCLUSION: CES accounted for 1/4 of ischemic stroke with a high risk of early death and long-term recurrence. Atrial fibrillation was the leading cause of CES. The association of VKA and anti-platelet agent should be avoided to reduce early death during acute stroke. PMID: 31155304 [PubMed - as supplied by publisher]

This study was carried out in accordance with the recommendations of “Guide for the Care and Use of Laboratory Animals, National Institutes of Health.” The protocol was approved by the “China Pharmaceutical University.” Surgical Preparation The mice were anesthetized with chloral hydrate (4% chloral hydrate, ip). The HF model was induced by CAL as previously reported (Gao et al., 2010). Successful ligation of the coronary artery was confirmed by the occurrence of ST-segment elevation in electrocardiogram. Sham operated mice were performed the same process except left CAL. After ligation, the heart...

There is a tough ongoing rivalry between drugs and catheters to conquer the commonest electrical chaos in human heart, namely Atrial fibrillation (AF). Mind you,the confusion about the importance of this arrhythmia is huge and real.Bulk of these episodes are transient , paroxysmal and do not require rigorous management.While stroke prevention seems to be the major aim and target , the real world scenario seems to tell  a different story. The nomenclature conundrum  AF may be classified as many ways a learned cardiologists can think . Often it’s done with reference to etiology, duration , rate, neural (sympa...

In conclusion, the present study demonstrated that TIGIT is a prominent negative immune regulator involved in immunosenescence. This novel finding is highly significant, as targeting TIGIT might be an effective strategy to improve the immune response and decrease age-related comorbidities.

CONCLUSIONS: On the basis of the reported association among CD, AS and CV diseases, we suggest to perform a more detailed CV risk assessment in all CD patients than what is currently being achieved in clinical practice, in order to scan and treat modifiable CV risk factors in these patients. In particular, we suggest to resort to instrumental techniques to detect AS in the subclinical stage, in order to prevent AS development and CV diseases in CD patients.

This study assessed the prevalence of grey hair in patients with coronary artery disease and whether it was an independent risk marker of disease. This was a prospective, observational study which included 545 adult men who underwent multi-slice computed tomography (CT) coronary angiography for suspected coronary artery disease. Patients were divided into subgroups according to the presence or absence of coronary artery disease, and the amount of grey/white hair. The amount of grey hair was graded using the hair whitening score: 1 = pure black hair, 2 = black more than white, 3 = black equals white, 4 = white more t...
