Health-related quality of life and hospitalizations in chronic thromboembolic pulmonary hypertension versus idiopathic pulmonary arterial hypertension: an analysis from the Pulmonary Hypertension Association Registry (PHAR).

Chronic thromboembolic pulmonary hypertension (CTEPH) is a rare, morbid, potentially curable subtype of pulmonary hypertension that negatively impacts health-related quality of life (HRQoL). Little is known about differences in HRQoL and hospitalization between CTEPH patients and idiopathic pulmonary arterial hypertension (IPAH) patients. Using multivariable linear regression and mixed effects models, we examined differences in HRQoL assessed by emPHasis-10 (E10) and SF-12 between CTEPH and IPAH patients in the Pulmonary Hypertension Association Registry, a prospective multicenter cohort of patients newly evaluated at a Pulmonary Hypertension Care Center. Multivariable negative binomial regression models were used to estimate incidence rate ratios (IRR) for hospitalization amongst the two groups. We included 461 IPAH patients and 169 CTEPH patients. Twenty-one percent of CTEPH patients underwent pulmonary thromboendarterectomy (PTE) before the end of follow-up. At baseline, patients with CTEPH had significantly worse HRQoL (higher E10 scores) (ß 2.83, SE 1.11, p = 0.01); however, differences did not persist over time. CTEPH patients had higher rates of hospitalization (excluding the hospitalization for PTE) compared to IPAH patients after adjusting for age, sex, body mass index, WHO functional class and six-minute walk distance (IRR 1.66, 95%CI 1.04-2.65, p = 0.03). CTEPH patients who underwent PTE had improved HRQoL as compared to those who were medically managed, but patients who underwent PTE were younger, had higher cardiac outputs and greater six-minute walk distances. In this large, prospective, multicenter cohort, CTEPH patients had significantly worse baseline HRQoL and higher rates of hospitalizations than those with IPAH. CTEPH patients who underwent PTE had significant improvements in HRQoL.

Heart Failure Hospitalization Trends During the Early Phase of the COVID 19 Pandemic

Purpose To quantify the change in heart failure (HF) hospitalizations observed in the early phase of the COVID-19 pandemic across a large, multi-center health care system. Methods MHealth Fairview encompasses four hospitals (one academic, three community-based) in the Minneapolis, Minnesota metro area. To compare HF hospitalization trends, two inpatient samples were created using HF discharges in the following time periods: pre COVID-19 (February 28, 2019-February 28, 2020) and post COVID-19 (April 1, 2020- May 15, 2020). March 2020 was excluded as this represented a transition point of the pandemic in the United States. Average number of discharges per day as well as demographics, diagnosis related group (DRG) codes, and inpatient mortality was then compared between the two inpatient HF samples. Results The pre COVID-19 group had 2,601 patients with an average of 7.1 (+/-3) discharges per day. The post COVID-19 group had 210 patients with an average of 4.7 (+/-1.7) discharges per day, which represented a 34% reduction in HF discharges (p <0.001). No statistically significant differences were observed between the pre and post COVID-19 inpatient samples with respect to age (76 vs. 75 years, p = 0.25), gender (46% vs. 48% male, p = 0.7), and DRG codes (DRG 291: 78% vs. 85% p = 0.15). Inpatient HF mortality pre and post COVID-19 was not significantly different (3% vs. 2.9%, p = 0.99). Conclusion

Does vitamin D deficiency increase the severity of COVID-19?

The severity of coronavirus 2019 infection (COVID-19) is determined by the presence of pneumonia, severe acute respiratory distress syndrome (SARS-CoV-2), myocarditis, microvascular thrombosis and/or cytokine storms, all of which involve underlying inflammation. A principal defence against uncontrolled inflammation, and against viral infection in general, is provided by T regulatory lymphocytes (Tregs). Treg levels have been reported to be low in many COVID-19 patients and can be increased by vitamin D supplementation. Low vitamin D levels have been associated with an increase in inflammatory cytokines and a significantly increased risk of pneumonia and viral upper respiratory tract infections. Vitamin D deficiency is associated with an increase in thrombotic episodes, which are frequently observed in COVID-19. Vitamin D deficiency has been found to occur more frequently in patients with obesity and diabetes. These conditions are reported to carry a higher mortality in COVID-19. If vitamin D does in fact reduce the severity of COVID-19 in regard to pneumonia/ARDS, inflammation, inflammatory cytokines and thrombosis, it is our opinion that supplements would offer a relatively easy option to decrease the impact of the pandemic.
