Heart Failure (HF) is a prevalent condition which places a substantial burden on healthcare systems worldwide. Medical management implemented with exercise training (ET) plays a role in prognostic and functional capacity improvement. The aim of this review is to determine the effect of exercise training (ET) on HFpEF and HFrEF patients as well as exercise modality recommendations in frail and sarcopenic subpopulations. Pharmacological therapy structures the cornerstone of management in HF reduced ejection fraction (HFrEF) and aids improved survival rates. Mortality reduction with pharmacological treatments in HF preserved ejection fraction (HFpEF) are yet to be established. Cardiac rehabilitation (CR) and ET can play an important role in both HFrEF and HFpEF. Preliminary findings suggest that CR significantly improves functional capacity, exercise duration, and quality of life. ET has shown beneficial effects on peak oxygen consumption (pVO2) and 6 min walk test distance in HFrEF and HFpEF patients, as well as a reduction in hospitalisation and mortality rates; however, the limited scope of larger trials reporting on this underscores the need for further research. ET also has been shown to have beneficial effects on depression and anxiety levels. High-intensity training (HIT) and moderate continuous training (MCT) have both shown benefits, while resistance exercise training and ventilatory assistance may also be beneficial. ET adherence rates are higher when enrolled to a supervised programme, but prescription rates remain low worldwide. Larger robust trials are required to determine ET’s effects on HF, as well as the most efficacious and personalised exercise prescriptions in HF subtypes.

Background: Transcatheter aortic valve implantation (TAVI) is associated with periprocedural and postprocedural morbidity and mortality. Currently, there is a paucity of risk stratification models for potential TAVI candidates. We employed the CHA2DS2-Vasc score to quantify the risk of 30-day mortality and morbidity in patients undergoing TAVI. Methods and results: A retrospective analysis of registry data for consecutive patients undergoing TAVI at 3 tertiary centres in Northwest England between 2008 and 2013. The CHA2DS2-Vasc score and its modification—the R2CHA2DS2-Vasc score, which includes pre-existing renal impairment and pre-existing conduction abnormality (right bundle branch block/left bundle branch block, RBBB/LBBB)—were calculated for all patients. A total of 313 patients with a mean age of 80 (79.1–80.8) years underwent TAVI. The implanted devices were either the CoreValve or the Edwards-SAPIEN prosthesis. The 30-day mortality was 14.3% in those with a CHA2DS2-Vasc score ≥6, whereas it was only 6.2% in those with a score <6 (p=0.04). Using the R2-CHA2DS2-Vasc score, the difference was more pronounced with a 30-day mortality of 22.6% in those patients with an R2-CHA2DS2-Vasc score ≥7 compared to 6.0% in those with a R2-CHA2DS2-Vasc score <7 (p=0.001). In multivariable Cox regression analyses, there was a significant and independent relationship between the CHA2DS2-Vasc score (hazard ratio (HR)= 2.71, (1.01 to 7.31); p<0.05) and the modified R2CHA2DS2-Vasc score (HR=4.27 (1.51 to 12.07); p=0.006) with 30-day mortality. Conclusions: Our study demonstrates the potential use of the CHA2DS2-Vasc or the R2CHA2DS2-Vasc score to quantify the risk of mortality in patients undergoing TAVI. This could have significant implications in terms of clinical as well as patients’ decision-making.

A twenty-three-year-old woman had an acute myocardial infarction during the early postpartum period successfully treated with intravenous strepto kinase. The possible mechanisms of postpartum myocardial infarction are re viewed, and the clinical implication for the use of streptokinase in this situation is discussed.

Background: Guidelines recommend patent foramen ovale (PFO) closure for secondary prevention after cryptogenic stroke in patients aged 18–65 years, but there is limited evidence to guide management of elderly adults. This research aims to assess the efficacy, safety and methodological quality of trials comparing secondary prevention PFO closure with medial therapy alone (MTA) in patients aged ≥ 60 years. Methods: A PubMed search identified four studies comparing PFO closure with MTA in elderly patients—PFOSK (South Korea), PT (Taiwan), DEFENSE (South Korea) and PFOG (Germany). Primary analyses evaluated study quality—patient selection, allocation, crossover and adherence. Secondary analyses compared recurrent cerebral ischaemia, mortality, new-onset atrial fibrillation (AF) and disability. Results: In 644 patients ≥ 60 years old, PFO closure was associated with a 45% (95% CI 0.35–0.86, p = 0.0091) reduction in recurrent cerebral ischaemia and an 85% (95% CI 0.05–0.49, p = 0.0016) reduction in mortality. Lower disability scores and increased incidence of new-onset AF (RR 2.15, 95% CI 1.07–4.32, p = 0.0306) was observed in closure groups. Study quality was limited by heterogeneity in medical regimens and closure protocols, crossover between treatment arms and imbalances in baseline characteristics, with closure groups generally younger and possessing larger shunt sizes. Conclusions: In patients aged ≥ 60 years, PFO closure appears to reduce the risk of the recurrence of ischaemic events and mortality, particularly in those with ‘high-risk’ PFO features. However, variability in study designs and low event rates limit certainty. Large, standardised trials are warranted to provide evidence for guideline recommendations in this population.

Heart Failure (HF) is a prevalent condition which places a substantial burden on healthcare systems worldwide. Pharmacological therapy structures the cornerstone of management in HF reduced ejection fraction (HFrEF), including angiotensin-converting enzyme inhibitors (ACE-I), angiotensin receptor-neprilysin inhibitors (ARNI), beta blockers (BB), mineralocorticoid receptor antagonists (MRA) and sodium/glucose co-transporter 2 (SGLT2) inhibitors, which all improve survival rates. Mortality reduction with pharmacological treatments in HF preserved ejection fraction (HFpEF) are yet to be established. Cardiac rehabilitation and exercise training can play an important role in both HFrEF and HFpEF. Cardiac rehabilitation significantly improves functional capacity, exercise duration and quality of life. Exercise training has shown beneficial effects on peak oxygen consumption (pVO2) and 6-minute walk test distance in HFrEF and HFpEF patients as well as a reduction in hospitalisation and mortality rates. ET also has been shown to have beneficial effects on depression and anxiety levels. High intensity training and moderate continuous training have both shown benefit, while resistance exercise training and ventilatory assistance may also be beneficial. ET adherence rates are higher when enrolled to a supervised programme but prescription rates remain low worldwide. Further research is required to establish the most efficacious exercise prescriptions in patients with HFrEF and HFpEF, but personalised exercise regimens should be considered as part of HF management.
