ObjectiveWe investigated whether serum high-sensitivity C reactive protein (hs-CRP) levels measured in an emergency department (ED) are associated with inhospital mortality in patients with cardiovascular disease (CVD).DesignA retrospective cohort study.SettingED of a teaching hospital in Japan.Participants12 211 patients with CVD aged ≥18 years who presented to the ED by an ambulance between 1 February 2006 and 30 September 2014 were evaluated.Main outcome measuresInhospital mortality.Results1156 patients had died. The inhospital mortality increased significantly with the hs-CRP levels (<3.0 mg/L: 7.0%, 95% CI 6.4 to 7.6; 3.1–5.4 mg/L: 9.6%, 95% CI 7.9 to 11.3: 5.5–11.5 mg/L: 11.2%, 95% CI 9.4 to 13.0; 11.6–33.2 mg/L: 12.3%, 95% CI 10.5 to 14.1 and ≥33.3 mg/L: 19.9%, 95% CI 17.6 to 22.2). The age-adjusted and sex-adjusted HR for total mortality was increased significantly in the three ≥5.5 mg/L groups compared with the <3.0 mg/L group (5.5–11.5 mg/L: HR=1.32, 95% CI 1.09 to 1.60, p=0.005; 11.6–33.2 mg/L: HR=1.38, 95% CI 1.14 to 1.65, p=0.001 and ≥33.3 mg/L: HR=2.15, 95% CI 1.84 to 2.51, p<0.001). Similar findings were observed for the CVD subtypes of acute myocardial infarction, heart failure, cerebral infarction and intracerebral haemorrhage. This association remained unchanged even after adjustment for age, sex and white cell count and withstood Bonferroni adjustment for multiple testing. When the causes of death were divided into primary CVD and non-CVD deaths, the association between initial hs-CRP levels and mortality remained significant, but the influence of hs-CRP levels was greater in non-CVD deaths than CVD deaths. The percentage of non-CVD deaths increased with hs-CRP levels; among the patients with hs-CRP levels ≥33.3 mg/L, non-CVD deaths accounted for 37.5% of total deaths.ConclusionOur findings suggest that increased hs-CRP is a significant risk factor for inhospital mortality among patients with CVD in an ED. Particular attention should be given to our finding that non-CVD death is a major cause of death among patients with CVD with higher hs-CRP levels.

Objectives : Novel coronavirus disease COVID-19 has emerged as a pandemic, claiming over 1,431,513 lives ( till Nov. 27,2020 ) worldwide involving 191 countries . The objective of the study is to evaluate age and gender as a risk factor for COVID -19 related mortality . Material and Methods : It is a retrospective cohort study , where the database of indoor COVID-19 positive patients was assessed for the study. Evaluation of the role of age and gender in mortality of COVID infection by comparing dataset of 2,142 indoor COVID positive patients with two outcome groups namely ,death and discharged groups was done. Results: The age comparison between two groups namely, death and discharged groups showed a median age of 60 years (IQR 50-70) for patients who died and 52 years (IQR 36–62) for the patients who recovered from COVID (p value-<0.001). There were 9 (0.65%) pediatric patients (<12 yrs) in the group of patients who recovered .For gender analysis (n=2129), COVID patients who died were 32.5%( n=692) ,out of which 63.6%(n=440) were males and 36.4%(n=252) were females. COVID positive patients in discharged group were 67.5%(n=1437),out of which 61.2%(n=880) were males and 38.8%(n=557) were females. There was no statistical difference between the two groups for mortality risk based on gender for COVID -19 infection (chi square value of 1.09, p value=.296) and the relative risk of death in males and females who died of COVID was 1.052 (95% CI=0.92-1.204). Conclusion: COVID-19 infection is showing predilection for male gender in both death and discharged group but the males and females are equally susceptible to the risk of death .
