Characteristics and 12-month outcome of patients with atrial fibrillation at a tertiary hospital in Botswana.

This study aimed at describing the clinical features and outcome of AF patients at a tertiary hospital in Botswana. METHODS: This prospective study was carried out in the Princess Marina Hospital in Gaborone, Botswana between August 2016 and July 2018. We consecutively enrolled 138 (97.8% black Africans) adult patients with electrocardiographically documented AF. Their baseline clinical and biomedical data were documented, and each patient was followed up for 12 months. The primary study outcome was 12-month all-cause mortality. RESULTS: The mean [standard deviation (SD) ] age of enrolled patients was 66.7 (17.2) years, and 63.8% were females. Common co-morbidities were hypertension (59.4%), rheumatic heart disease (37.7%) and heart failure (35.5%). Stroke/transient ischaemic attack (TIA) (21.7%) and obesity (34.8%) were also prevalent. Compared to patients with non-valvular AF, those with valvular AF were more likely to be female (82 vs 55%, p = 0.003), younger (60 vs 75 years, p

Conclusion Swim training, a sport characterized by unique cardiac loading conditions, stimulates eccentric LV remodeling with the concomitant augmentation of systolic twist and diastolic relaxation. This volume-mediated cardiac remodeling appears to result in greater systolic susceptibility to acute afterload challenge. Further work is required to establish how training-induced changes in function translate to human performance and whether these are accompanied by physiologic trade-offs with relevance to common forms of heart disease.

Conclusions After accounting for baseline PA, greater positive changes in leisure-time PA levels were associated with a more eccentric-type of LV remodeling pattern over 10 yr. The clinical implications of such findings remain to be determined.

Purpose Low-attenuation muscle (LAM) area at mid-thigh, a computed tomography (CT)–derived index of intramuscular lipids, is associated with insulin resistance, obesity, and type 2 diabetes. The present study aimed at testing the hypothesis that changes in LAM area in trunk muscles from a single abdominal scan could provide relevant information to evaluate the effects of a lifestyle intervention without the use of a mid-thigh CT scan. Methods Cardiometabolic risk variables, including waist circumference, lipoprotein–lipid profile, glucose tolerance, and cardiorespiratory fitness, were assessed in a sample ...

CONCLUSIONS: More than half of middle-aged women without cardiovascular symptoms present alterations in one or more exercise testing parameters. Alterations in the functional capacity or heart rate behavior, as verified by exercise testing, are associated with age, smoking, an overweight status and obesity.

ConclusionFrequency and impact of vestibular symptoms in patients visiting the ED were higher than previously reported, and life-threatening aetiologies such as strokes are common. Therefore, awareness among physicians regarding the importance of vestibular symptoms has to be improved.
