Background: Relative fat mass (RFM) had been recently developed. We aimed to examine RFM predictability to various cardiometabolic risk factors, compared to BMI. Methods: Observational, cohort study, among patients who visited the Rambam Periodic Examinations Institute (RPEI). We compared the correlation of BMI and RFM to hypertension, impaired fasting glucose, high LDL, low HDL and metabolic syndrome, by gender. Results: During study years, 20 167 patients visited the RPEI and included in the trial. Compared to BMI, RFM showed significantly better predictability (odds ratio [OR], [95% confidence interval (CI), P value]) of high LDL [1.618 (1.441–1.816, P < 0.001) vs. 0.732 (0.67–0.8, P < 0.001) in men; 1.572 (1.377–1.794, P < 0.001) vs. 0.938 (0.849–1.163, P = 0.94) in women], low HDL [2.944 (2.569–3.373, P < 0.001) vs. 2.177 (2–2.369, P < 0.001) in men, 2.947 (2.519–3.448, P < 0.001) vs. 1.9 (1.658–2.176, P < 0.001) in women], high triglycerides [4.019 (3.332–4.847, P < 0.001) vs. 1.994 (1.823–2.181, P < 0.001) in men, 3.93 (2.943–5.247, P < 0.001) vs. 2.24 (1.887–2.62, P < 0.001) in women] and metabolic syndrome [7.479, (4.876–11.47, P < 0.001) vs. 3.263 (2.944–3.616, P < 0.001) in men, 16.247 (8.348–31.619, P < 0.001) vs. 5.995 (5.099–7.048, P < 0.001) in women]. There was no significant difference in the predictability of BMI and RFM to hypertension and diabetes mellitus. Conclusion: RFM provides high predictability for dyslipidemias and metabolic syndrome.

Aims/hypothesis: Our study aimed to examine the trends in diabetes-related mortality in urban and rural areas in the USA over the past two decades. Methods: We examined the trends in diabetes-related mortality (as the underlying or a contributing cause of death) in urban and rural areas in the USA between 1999 and 2019, using the CDC WONDER Multiple Cause of Death database. We estimated the 20 year trends of the age-adjusted mortality rate (AAMR) per 100,000 population in urban vs rural counties. Results: The AAMR of diabetes was higher in rural than urban areas across all subgroups. In urban areas, there was a significant decrease in the AAMR of diabetes as the underlying (−16.7%) and contributing (−13.5%) cause of death (ptrend<0.001), which was not observed in rural areas (+2.6%, +8.9%, respectively). AAMRs of diabetes decreased more significantly in female compared with male individuals, both in rural and urban areas. Among people younger than 55 years old, there was a temporal increase in diabetes-related AAMR (+13.8% to +65.2%). While the diabetes-related AAMRs of American Indian patients decreased in all areas (−19.8% to −40.5%, all ptrend<0.001), diabetes-related AAMRs of Black and White patients decreased significantly in urban (−26.6% to −28.3% and −10.7% to −15.4%, respectively, all ptrend<0.001) but not rural areas (−6.5% to +1.8%, +2.4% to +10.6%, respectively, ptrend NS, NS, NS and <0.001). Conclusions/interpretation: The temporal decrease in diabetes-related mortality in the USA has been observed only in urban areas, and mainly among female and older patients. A synchronised effort is needed to improve cardiovascular health indices and healthcare access in rural areas and to decrease diabetes-related mortality. Graphical

Early reports described decreased admissions for acute cardiovascular events during the SarsCoV-2 pandemic. We aimed to explore whether the lockdown enforced during the SARSCoV-2 pandemic in Israel impacted the characteristics of presentation, reperfusion times, and early outcomes of ST-elevation myocardial infarction (STEMI) patients. A multicenter prospective cohort comprising all STEMI patients treated by primary percutaneous coronary intervention admitted to four high-volume cardiac centers in Israel during lockdown (20/3/2020–30/4/2020). STEMI patients treated during the same period in 2019 served as controls. The study comprised 243 patients, 107 during the lockdown period of 2020 and 136 during the same period in 2019, with no difference in demographics and clinical characteristics. Patients admitted in 2020 had higher admission and peak troponin levels, had a 2.4 fold greater likelihood of Door-to-balloon times> 90 min (95%CI: 1.2–4.9, p = 0.01) and 3.3 fold greater likelihood of pain-to-balloon times> 12 hours (OR 3.3, 95%CI: 1.3–8.1, p<0.01). They experienced higher rates hemodynamic instability (25.2% vs 14.7%, p = 0.04), longer hospital stay (median, IQR [4, 3–6 Vs 5, 4–6, p = 0.03]), and fewer early (<72 hours) discharge (12.4% Vs 32.4%, p<0.001). The lockdown imposed during the SARSCoV-2 pandemic was associated with a significant lag in the time to reperfusion of STEMI patients. Measures to improves this metric should be implemented during future lockdowns.

Background: Diagnosis of AF-induced cardiomyopathy can be challenging and relies on ruling out other causes of cardiomyopathy and, after restoration of sinus rhythm, recovery of left ventricular (LV) function. The aim of this study was to identify clinical and echocardiographic predictors for developing cardiomyopathy with systolic dysfunction in patients with atrial tachyarrhythmia. Methods: This retrospective study was conducted in a large tertiary care centre and compared patients who experienced deterioration of LV ejection fraction (EF) during paroxysmal AF, demonstrated by precardioversion transoesophageal echocardiography with patients with preserved LV function during AF. All patients had documented preserved LVEF at baseline (EF >50%) while in sinus rhythm. Results: Of 482 patients included in the final analysis, 80 (17%) had reduced and 402 (83%) had preserved LV function during the precardioversion transoesophageal echocardiography. Patients with reduced LVEF were more likely to be men and to have a more rapid ventricular response during AF or atrial flutter (AFL). A history of prosthetic valves was also identified as a risk factor for reduced LVEF. Patients with reduced LVEF also had higher incidence of tricuspid regurgitation and right ventricular dysfunction. Conclusion: In ‘real-world’ experience, male patients with rapid ventricular response during paroxysmal AF or AFL are more prone to LVEF reduction. Patients with prosthetic valves are also at risk for LVEF reduction during AF/AFL. Finally, tricuspid regurgitation and right ventricular dysfunction may indicate relatively long-standing AF with an associated reduction in LVEF.

Background: In the past few decades, diabetes‐related cardiovascular mortality has been steadily declining. However, the impact of the COVID19 pandemic on this trend has not been previously defined. Methods and Results: Diabetes‐related cardiovascular mortality data were extracted for each year between 1999 and 2020 from the Centers for Disease Control and Prevention Wide‐Ranging Online Data for Epidemiologic Research (WONDER) database. Regression analysis was used to calculate the trend in the 2 decades before the pandemic (1999–2019) and thereby estimate the excess cardiovascular mortality in 2020. There was a 29.2% fall in the diabetes‐related cardiovascular age‐adjusted mortality rate between 1999 to 2019, largely driven by a 41% decrease in ischemic heart disease deaths. In comparison to 2019, there was an overall 15.5% increase in the diabetes‐related cardiovascular age‐adjusted mortality rate in the first year of the pandemic, mainly due to a 14.1% rise in ischemic heart disease deaths. Younger patients (under 55 years) and the Black population experienced the greatest increase in diabetes‐related cardiovascular age‐adjusted mortality rate (24.0% and 25.3%, respectively). Trend analysis estimated 16 009 excess diabetes‐related cardiovascular deaths in 2020, with the majority due to ischemic heart disease (8504). Black and Hispanic or Latino populations had at least one‐fifth of their 2020 diabetes‐related cardiovascular age‐adjusted mortality rate as excess deaths (22.3% and 20.2%, respectively). Conclusions: There was a sharp rise in diabetes‐related cardiovascular mortality during the first pandemic year. Black, Hispanic or Latino, and young people showed the largest increases in diabetes‐related cardiovascular mortality. Targeted health policies could help address the disparities observed in this analysis.
