Potassium Disturbances and Risk of Ventricular Fibrillation Among Patients With ST-Segment-Elevation Myocardial Infarction

Background Potassium disturbances per se increase the risk of ventricular fibrillation (VF). Whether potassium disturbances in the acute phase of ST-segment-elevation myocardial infarction (STEMI) are associated with VF before primary percutaneous coronary intervention (PPCI) is uncertain. Methods and Results All consecutive STEMI patients were identified in the Eastern Danish Heart Registry from 1999 to 2016. Comorbidities and medication use were assessed from Danish nationwide registries. Potassium levels were collected immediately before PPCI start. Multivariate logistic models were performed to determine the association between potassium and VF. The main analysis included 8624 STEMI patients of whom 822 (9.5%) had VF before PPCI. Compared with 6693 (77.6%) patients with normokalemia (3.5-5.0 mmol/L), 1797 (20.8%) patients with hypokalemia (5.0 mmol/L) were older with more comorbidities. After adjustment, patients with hypokalemia and hyperkalemia had a higher risk of VF before PPCI (odds ratio 1.90, 95% CI 1.57-2.30, P<0.001) and (odds ratio 3.36, 95% CI 1.95-5.77, P<0.001) compared with normokalemia, respectively. Since the association may reflect a post-resuscitation phenomenon, a sensitivity analysis was performed including 7929 STEMI patients without VF before PPCI of whom 127 (1.6%) had VF during PPCI. Compared with normokalemia, patients with hypokalemia had a significant association with VF during PPCI (odds ratio 1.68, 95% CI 1.01-2.77, P=0.045) after adjustment. Conclusions Hypokalemia and hyperkalemia are associated with increased risk of VF before PPCI during STEMI. For hypokalemia, the association may be independent of the measurement of potassium before or after VF

Initiation of SGLT2 inhibitors and GLP-1 receptor agonists according to level of frailty in people with type 2 diabetes and cardiovascular disease in Denmark: a cross-sectional, nationwide study

Background: Whether frailty influences the initiation of two cardioprotective diabetes drug therapies (ie, SGLT2 inhibitors and GLP-1 receptor agonists) in people with type 2 diabetes and cardiovascular disease is unknown. We aimed to assess rates of initiation of SGLT2 inhibitors and GLP-1 receptor agonists according to frailty in people with type 2 diabetes and cardiovascular disease. Methods: For this cross-sectional, nationwide study, all people with type 2 diabetes and cardiovascular disease in Denmark between Jan 1, 2015, and Dec 31, 2021, from six Danish health-data registers were identified. People younger than 40 years, with end-stage renal disease, with registered contraindications to SGLT2 inhibitors or GLP-1 receptor agonists, or with previous use of either drug therapy were excluded. The Hospital Frailty Risk Score was used to categorise people as either non-frail, moderately frail, or severely frail. Cox proportional hazards models were used to analyse the association between frailty and initiation of an SGLT2 inhibitor or a GLP-1 receptor agonist. Findings: Of 119 390 people with type 2 diabetes and cardiovascular disease, 103 790 were included. Median follow-up time was 4·5 years (IQR 2·7–6·1) and median age across the three frailty groups was 71 years (64–79). 65 959 (63·6%) of 103 790 people were male and 37 831 (36·5%) were female. At index date, 66 910 (64·5%) people were non-frail, 29 250 (28·2%) were moderately frail, and 7630 (7·4%) were severely frail. Frailty was associated with a significantly lower probability of initiating therapy with an SGLT2 inhibitor or a GLP-1 receptor agonist than in people who were non-frail (moderately frail hazard ratio 0·91, 95% CI 0·88–0·94, p&lt;0·0001; severely frail 0·75, 0·70–0·80, p&lt;0·0001). This association persisted after adjustment for age, sex, socioeconomic status, year of inclusion, duration of type 2 diabetes, duration of cardiovascular disease, polypharmacy, and comorbidity. Interpretation: In people with type 2 diabetes and cardiovascular disease in Denmark, frailty was associated with a significantly lower probability of SGLT2-inhibitor or GLP-1 receptor-agonist initiation, despite their benefits. Formulating clear and updated guidelines on the use of SGLT2 inhibitors and GLP-1 receptor agonists in people who are frail with type 2 diabetes and cardiovascular disease should be a priority.

Cancer Incidence, Mortality, Years of Life Lost, Years Lived With Disability, and Disability-Adjusted Life Years for 29 Cancer Groups From 2010 to 2019: A Systematic Analysis for the Global Burden of Disease Study 2019.

The Global Burden of Diseases, Injuries, and Risk Factors Study 2019 (GBD 2019) provided systematic estimates of incidence, morbidity, and mortality to inform local and international efforts toward reducing cancer burden. To estimate cancer burden and trends globally for 204 countries and territories and by Sociodemographic Index (SDI) quintiles from 2010 to 2019. The GBD 2019 estimation methods were used to describe cancer incidence, mortality, years lived with disability, years of life lost, and disability-adjusted life years (DALYs) in 2019 and over the past decade. Estimates are also provided by quintiles of the SDI, a composite measure of educational attainment, income per capita, and total fertility rate for those younger than 25 years. Estimates include 95% uncertainty intervals (UIs). In 2019, there were an estimated 23.6 million (95% UI, 22.2-24.9 million) new cancer cases (17.2 million when excluding nonmelanoma skin cancer) and 10.0 million (95% UI, 9.36-10.6 million) cancer deaths globally, with an estimated 250 million (235-264 million) DALYs due to cancer. Since 2010, these represented a 26.3% (95% UI, 20.3%-32.3%) increase in new cases, a 20.9% (95% UI, 14.2%-27.6%) increase in deaths, and a 16.0% (95% UI, 9.3%-22.8%) increase in DALYs. Among 22 groups of diseases and injuries in the GBD 2019 study, cancer was second only to cardiovascular diseases for the number of deaths, years of life lost, and DALYs globally in 2019. Cancer burden differed across SDI quintiles. The proportion of years lived with disability that contributed to DALYs increased with SDI, ranging from 1.4% (1.1%-1.8%) in the low SDI quintile to 5.7% (4.2%-7.1%) in the high SDI quintile. While the high SDI quintile had the highest number of new cases in 2019, the middle SDI quintile had the highest number of cancer deaths and DALYs. From 2010 to 2019, the largest percentage increase in the numbers of cases and deaths occurred in the low and low-middle SDI quintiles. The results of this systematic analysis suggest that the global burden of cancer is substantial and growing, with burden differing by SDI. These results provide comprehensive and comparable estimates that can potentially inform efforts toward equitable cancer control around the world.Funding/Support: The Institute for Health Metrics and Evaluation received funding from the Bill & Melinda Gates Foundation and the American Lebanese Syrian Associated Charities.

Nationwide cardiovascular disease admission rates during a second COVID-19 lockdown

Societal lockdowns during the first wave of the COVID-19 pandemic were associated with decreased admission rates for acute cardiovascular conditions worldwide. In this nationwide Danish study of the first five weeks of a second pandemic lockdown, incidence of new-onset heart failure and atrial fibrillation remained stable, but there was a significant drop in new-onset ischemic heart disease and ischemic stroke during the fourth week of lockdown, which normalized promptly. The observed drops were lower compared to the first Danish lockdown in March 2020; thus, our data suggest that declines in acute CVD admission rates during future lockdowns are avoidable
