Background Severe coronavirus disease (COVID‐19) is characterized by a pro‐inflammatory state with high mortality. Statins have anti‐inflammatory effects and may attenuate the severity of COVID‐19. Methods and Results An observational study of all consecutive adult patients with COVID‐19 from March 1, 2020 to May 2, 2020 admitted to a single‐center located in Bronx, New York. Patients were grouped as those that did and did not receive a statin and in‐hospital mortality was compared by competing events regression. In addition, propensity score matching and inverse probability treatment weighting (IPTW) were used in survival models to examine the association between statin use and death during hospitalization. A total of 4,252 patients were admitted with COVID‐19. Diabetes modified the association between statin use and in‐hospital mortality. Patient with diabetes on a statin (n=983) were older (69±11 vs. 67±14 years, p<0.01), had lower inflammatory markers (C‐reactive protein: 10.2, IQR: 4.5‐18.4 vs. 12.9, IQR: 5.9‐21.4 mg/dl, p<0.01) and reduced cumulative in‐hospital mortality (24% vs. 39%, p<0.01) than those not on a statin (n=1,283). No difference in hospital mortality was noted in patients without diabetes on or off statin (20% vs. 21%, p=0.82). Propensity score matching (HR=0.88, 95% CI 0.83‐0.94, p<0.01) and IPTW (HR=0.88, 95% CI 0.8 4 ‐0.92, p<0.01) showed a 12% lower risk of death during hospitalization for statin users than non‐users. Conclusions Statin use was associated with reduced in‐hospital mortality from COVID‐19 in patients with diabetes. These findings, if validated, may further reemphasize administration of statins to patients with diabetes during the COVID‐19 era.
Awareness of the importance of sleep-related disorders in patients with cardiovascular diseases is growing. In particular, sleep-disordered breathing, short sleep time, and low sleep quality are frequently reported by patients with heart failure (HF). Sleep-disordered breathing, which includes obstructive sleep apnoea (OSA) and central sleep apnoea (CSA), is common in patients with HF and has been suggested to increase the morbidity and mortality in these patients. Both OSA and CSA are associated with increased sympathetic activation, vagal withdrawal, altered haemodynamic loading conditions, and hypoxaemia. Moreover, OSA is strongly associated with arterial hypertension, the most common risk factor for cardiac hypertrophy and failure. Intrathoracic pressure changes are also associated with OSA, contributing to haemodynamic alterations and potentially affecting overexpression of genes involved in ventricular remodelling. HF treatment can decrease the severity of both OSA and CSA. Indeed, furosemide and spironolactone administration, exercise training, cardiac resynchronization therapy, and eventually heart transplantation have shown a positive effect on OSA and CSA in patients with HF. At present, whether CSA should be treated and, if so, which is the optimal therapy is still debated. By contrast, more evidence is available on the beneficial effects of OSA treatment in patients with HF.
An increasing number of end-stage heart failure patients are now implanted with continuous-flow left ventricular assist devices (CF-LVADs). Although this therapeutic approach is associated with improved clinical outcomes, continuous flow physiology reduces arterial pulse pressure and pulsatility to an extent that is unique to this population. Recent data suggest that high blood pressure (BP) contributes to life-threatening complications such as pump thrombosis and stroke of CF-LVAD patients. However, limited understanding of the distinct hemodynamics of these pumps makes measurement and, consequently, medical management of BP quite challenging. Here, we review the evolution of LVAD design, the impact of CF-LVAD flow, and “artificial pulse” technology on hemodynamics and BP measurement, as well as suggest new approaches for the assessment and interpretation of the unique physiology of modern LVADs.
Recently published research contends that anxiety and depression are more common in asthmatic patients than in the general population. Particular psychological profiles could even be a risk factor contributing to deaths caused by asthma. The purpose of our research was to evaluate the anxiety and depression level in a population of 80 asthmatic patients who were treated in our department, and to judge whether data collected on psychological profiles of these asthmatic patients can be of any significance when dealing with their pathology. The study consisted of 40 patients suffering from chronic viral hepatitis B or C, and 40 healthy subjects who served as a control group. Both sets of patients were homogeneous with regard to sex, age and education. All subjects were tested for anxiety and depression levels with the S.T.A.I. and Zung questionnaires. A structured questionnaire was employed to assess the daily approach to living with the disease only in asthmatic patients. The anxiety and depression levels were noticeably higher in asthmatic patients than in patients with chronic liver disease and healthy subjects. In particular, 34 asthmatic patients scored higher than the S.T.A.I. cut-off (40/80) and 27 attained the same results in the Zung questionnaire. Results from the asthmatic population and healthy subjects illustrated that women had a higher incidence of anxiety and depression compared to men, although no statistically significant relationship between sex and questionnaire results was apparent in patients with liver disease. In the year before assessment, hospitalization and emergency treatment due to asthmatic exacerbation was correlated in females with a high incidence of anxiety. Additionally, the asthmatic population's level of education is significantly related to the incidence of anxiety and depression. With higher education, incidence of depression and anxiety decreased. This result was not apparent in control groups. The results of our study were: (1) we confirmed that asthmatic pathology is associated with an increase in incidence of anxiety and depression, whose presence and seriousness should be taken into consideration in therapeutic programmes when dealing with a patient; (2) we indicated that a specific approach towards therapy is crucial when dealing with an asthmatic patient; (3) we suggested how important it is to identify categories of patients that require more care because of their psychological profile. These findings should provide for the optimal use of informational resources with important applications for educational programmes and the future treatment of the asthmatic population.
