The rapid spread of a novel coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has led to an ongoing pandemic of coronavirus disease 2019 (COVID-19). Recently, angiotensin-converting enzyme 2 (ACE2) has been shown to be a functional receptor for SARS-CoV-2 to enter host target cells. ⋯ Importantly, however, there is no clinical or experimental evidence supporting that ARBs and ACEIs either augment the susceptibility to SARS-CoV-2 or aggravate the severity and outcomes of COVID-19 at present. Until further data are available, it is recommended that ARB and ACEI medications be continued for the treatment of patients with cardiovascular disease and hypertension, especially those at high risk, according to guideline-directed medical therapy based on the currently available evidence.

Review
The biological function of ELABELA and APJ signaling in the cardiovascular system and pre-eclampsia.
Pre-eclampsia (PE) is a pregnancy-specific syndrome that is characterized by hypertension and proteinuria. The etiology of PE is not completely understood but is believed to involve placental insufficiency and maternal vascular damage. ⋯ A recent study linked deficient ELABELA signaling and the development of PE, though the molecular mechanism remains largely unknown. In this review, we summarize the biological function of the ELABELA and APJ system in cardiovascular homeostasis and discuss the potential mechanisms by which ELABELA and APJ regulate placenta trophoblast invasion and vascular functions and participate in the development of PE.

Meta Analysis Comparative Study
Angiotensin-converting enzyme inhibitors versus angiotensin receptor blockers in hypertensive patients with myocardial infarction or heart failure: a systematic review and meta-analysis.
Angiotensin-converting enzyme inhibitors (ACEIs) are considered primary drugs for the secondary prevention of myocardial infarction (MI), and angiotensin receptor blockers (ARBs) are used when ACEIs cannot be tolerated. However, it is unclear whether ACEIs or ARBs are more appropriate first-line drugs in hypertensive patients with MI or heart failure (HF). The present study aimed to compare the effects of ACEIs and those of ARBs in these patients. ⋯ There were no significant differences between ACEIs and ARBs for all outcomes, except adverse events. Study discontinuation owing to adverse events was significantly more common with ACEIs than with ARBs. Among hypertensive patients with MI or HF, it appears desirable to select the most appropriate drugs, ACEIs or ARBs, in each case by considering the function level, patient background, comorbidity presence, blood pressure target, drug price and other such factors comprehensively in addition to considering tolerability.

The effect of dietary sodium (salt) on cardiovascular disease (CVD) has been debated for a long time. The present study aims to explore whether salt intake affects the risk of cardiovascular disease in the Chinese population. Data from a prospective cohort study that included 954 men and women aged 35-59 years at baseline from four urban and rural population samples in China were used. ⋯ However, this trend was not significant after adjusting for the baseline systolic blood pressure and antihypertensive medication use (P for trend = 0.171). No significant associations were found between sodium excretion and all-cause, cancer-related or other-cause mortality. High urinary sodium excretion was independently associated with an increased risk of cardiovascular disease in the general Chinese population.

Randomized Controlled Trial
Risk of incident chronic kidney disease is better reduced by bedtime than upon-awakening ingestion of hypertension medications.
This trial investigated whether therapy with the entire daily dose of ≥1 hypertension medications at bedtime exerts a greater reduction in the risk of incident chronic kidney disease (CKD) than therapy with all medications upon awakening. We conducted a prospective, open-label, blinded endpoint trial of 2078 hypertensive patients without CKD (1017 men/1061 women, 53.6 ± 13.7 years of age) randomized to ingest all their prescribed hypertension medications upon awakening (n = 1041) or the entire daily dose of ≥1 of those medications at bedtime (n = 1037). ⋯ Greater benefit was observed for bedtime than awakening treatment, with angiotensin converting enzyme inhibitors and angiotensin receptor blockers. In hypertensive patients without CKD, ingestion of ≥1 BP-lowering medications at bedtime, mainly those modulating or blocking the effects of angiotensin II, compared with ingestion of all such medications upon-awakening, resulted in improved ambulatory BP control (significant further decrease of asleep BP and enhanced sleep-time relative BP decline) and reduced risk of incident CKD.
