Tolerability and efficacy of sacubitril/valsartan in clinical practice.
Heart failure (HF) is a major cause of morbidity and mortality. Sacubitril/valsartan has demonstrated reductions in HF hospitalisation, and all-cause mortality in patients with heart failure with reduced ejection fraction. ⋯ Sacubitril/valsartan is a much needed therapeutic advancement in the treatment of HF. Our study indicates it is well tolerated with improvements in cardiac function and symptoms. Sacubitril/valsartan could redefine the definition of 'optimal medical therapy' when assessing patients for device based therapies.

ReviewTracking of brachial and central aortic systolic pressure over the normal human lifespan: insight from the arterial pulse waveforms.
Despite multiple studies, it has not been possible to account for the normal changes of blood pressure that occur from infancy to old age. We sought a comprehensive explanation, by linking brachial pressure with the well documented changes in the arterial pulse waveform, whose peak and nadir determine systolic, diastolic and pulse pressure in brachial arteries. Changes in humans arterial pulse wave contour from birth to old age can be readily explained on (i) growth, with increasing length of the body from birth to adolescence, and adult height maintained thereafter, and (ii) degeneration and dilation of the aorta from elastic fibre fracture throughout life, causing progressive increase in aortic pressure wave amplitude from early return of wave reflection, and summation of incident with reflected waves in systole. These changes throughout life complement arterial pulse waveform analysis and explain brachial cuff pressure values, with optimal pulse wave pattern for cardiac interaction apparent in adolescence.

Unexpected high frequency of early mortality in COVID-19: a single-centre experience during the first wave of the pandemic.
We report the high frequency of early mortality in COVID-19 patients (48.6% of 72 deaths). Early deaths were not explained by differences in age, sex and comorbidities, but they had a more severe disease at hospital admission compared with late deaths. These data highlight the importance of outpatient monitoring for the early identification of COVID-19 patients who require hospital admission.
