Quality of care among patients diagnosed with atrial fibrillation in Greenland

This cross-sectional study sought to assess the prevalence of atrial fibrillation (AF) diagnosis in Greenland among various age groups and examine the corresponding quality of care. We collected data from Greenland’s electronic medical records and evaluated the quality of care using six internationally recommended indicators, which are: percentage of AF patients with an assessment of smoking status within the previous year, an assessment of body mass index within the previous year, assessment of blood pressure within the previous year, measurement of thyroid stimulating hormone (TSH), treatment with an anticoagulant and percentage of patients with a measurement of serum-creatinine. We found the prevalence of AF among patients aged 20 years or older in Greenland to be 1.75% (95% CI 1.62–1.88). We found an increasing prevalence of AF with age and a greater proportion of men than women until the age of 74 years. Our study suggests that the associated quality of care could be higher as the requirement of only one of the six quality indicators was met. A lack of registration may partly explain this, and initiatives to improve the quality of care are recommended.</p

Prevalence and clinical features of heart failure in Greenland

ABSTRACTHeart Failure (HF) constitutes a significant burden for healthcare around the world. In Greenland, risk factors like smoking, diabetes, and obesity are prevalent. Yet, the prevalence of HF remains unexplored. This register-based cross-sectional study uses data from the national medical record in Greenland to estimate the age- and gender-specific prevalence of HF and to describe the characteristics of patients with HF in Greenland. A total of 507 patients (26% women) with a mean age of 65 years were included based on a diagnosis of HF. The overall prevalence was 1.1% and higher among men compared to women (1.6% vs. 0.6%, p < 0.05). The highest prevalence was among men above 84 years (11.1%). More than half (53%) had a body mass index above 30 kg/m2 and 43% were current daily smokers. The proportion diagnosed with ischaemic heart disease (IHD) was 33%. The overall prevalence of HF in Greenland is consistent with that in other high-income countries, yet high among men in some age groups, compared to Danish men. Almost half the patients were obese and/or smokers. A low prevalence of IHD was observed indicating that other factors may play a role in developing HF among Greenlanders

Heart disease among Greenlandic children and young adults: a nationwide cohort study

Abstract Background The incidences of heart disease (HD) and congenital heart disease (CHD) among Inuit in Greenland (GL) and Denmark (DK) are unknown. This study aims to estimate incidence rates (IRs) of HD and CHD among the young Inuit populations in Greenland and Denmark compared with rates among young non-Inuit populations in the same countries. Methods A register-based nationwide cohort including all individuals living in Greenland and Denmark from birth to age &amp;lt;40 years through 1989–2014 was formed. Ethnicity was considered Inuit/mixed if at least one parent was registered as being born in Greenland. Information on HD and CHD hospitalization was obtained from national inpatient registers using ICD-8 and ICD-10 codes. Results HD IR was lower among individuals living in Greenland compared with those living in Denmark, [73.35GL (95% confidence interval (CI) 68.07 to 79.03)] vs [88.07DK (95% CI 87.38 to 88.76)], whereas CHD IRs were almost similar in the two countries [IR 34.44GL (95% CI 30.89 to 38.40) vs IR 34.67DK (95% CI 34.24 to 35.10)]. Being of Inuit/mixed ethnicity was associated with an increased risk of both HD and CHD compared with non-Inuit in Greenland and Denmark [adjusted hazard ratio HD 2.07GL (95% CI 1.25 to 3.42)] and CHD [2.92GL (95% CI 1.34 to 6.38)]. Conclusion HD IR was lower in individuals living in Greenland compared with individuals living in Denmark, whereas the CHD IRs were almost the same for both countries. However, the risk of HD including CHD was higher among individuals of Inuit/mixed ethnicity compared with non-Inuit in both countries, suggesting a role of ethnicity among children and younger adults. </jats:sec

Dyslipidemia and the preventive potential in the Greenlandic population

Background: Low-density lipoprotein cholesterol (LDL-C) is a well-established risk factor for development of cardiovascular diseases. Based on available clinical data, we aimed to investigate the plasma lipid profile in the Greenlandic population, the proportion on cholesterol-lowering treatment and the adherence to local indications for cholesterol-lowering therapy. Methods: This is an observational cross-sectional study of the adult (≥21 years) Greenlandic population with focus on clinically determined lipid levels from 2017 to early 2022. We investigated levels of dyslipidemia and assessed cholesterol-lowering medication usage in individuals with an indication according to current Greenlandic guidelines, which include a) LDL-C >5 mmol/l, b) diabetes, c) diagnosed atherosclerotic disease and 4) a SCORE2 >7.5%. Results: In the adult Greenlandic population of 40,565 individuals a lipid profile was available in 13,895 with a mean LDL-C of 3.0 mmol/L and 976 (7%) had a LDL-C >5 mmol/l. One or more indications for cholesterol-lowering medication was present in 3988 individuals and a total of 5464 adult Greenlanders either fulfilled local criteria for statin therapy or received a statin (some without current indication) and among these, 2232 (41%) individuals received no statin. Conclusion: These findings indicate that clinically significant dyslipidemia is common in the adult Greenlandic population and that the cardiovascular preventive potential of cholesterol-lowering therapy is currently underutilized
