Our findings indicate that exercise training may improve the functional status of VAD recipients even at a later period after implantation and thus, may have additional importance in cases of destination therapy.
The results of this pilot study suggest that prophylactic administration of iloprost may effectively prevent CMN, but higher dosages are connected with substantial tolerability issues.
The unloaded failing myocardium responded to physical training by enhancing thyroid hormone signalling. This response was associated with an up-regulation of Akt and suppression of JNK activation.
Cardiac allograft rejection (CAR) may occur after transplantation and remains silent, until hemodynamic deterioration takes place. Endomyocardial biopsy (EMB) is applied to early detect CAR. Although, flexible bioptoms have decreased the incidence of lethal complications, EMB remains an invasive procedure carrying risk of tamponade and permanent heart block. Therefore, a new non-invasive approach is needed. Areas covered: AlloMap molecular expression testing and graft-derived cell-free DNA (GcfDNA) test can be used as blood indices of acute and chronic CAR, respectively. Among diagnostic techniques, only echocardiography and cardiovascular magnetic resonance (CMR) have shown a strong correlation with EMB. Echocardiography is bedside, cost and time saving. However, the currently used indices are insensitive markers of CAR. Global longitudinal strain (GLS) can diagnose the subclinical CAR and be used together with EMB to monitor acute CAR. CMR can improve our diagnostic accuracy using T2STIR, T1, T2 mapping, early/late gadolinium enhancement and functional assessment. Expert commentary: A new non-invasive approach in asymptomatic transplanted patients should be based on a serial assessment of AlloMap, GcfDNA testing, echocardiographic and CMR indices that will guide the indication for EMB. In symptomatic patients immediate EMB is the approach of choice, since they have high likelihood for CAR.
Malignant arrhythmias during coronary angiography consist a complication of the procedure. Clinicians should be aware that intracoronary infusion of contrast medium can lead to physiological changes that lower the ventricular fibrillation threshold.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
