All-cause mortality and cardiovascular events in a Spanish nonagenarian cohort according to type 2 diabetes mellitus status and established cardiovascular disease.

BACKGROUND: Despite the progressive aging of the population in industrialized countries, few studies have focused on the natural history of cardiovascular disease in the very old, and recommendations on prevention of cardiovascular disease in this population are lacking. We aimed to analyze all-cause mortality and cardiovascular events according to prevalent type 2 diabetes mellitus and established cardiovascular disease in nonagenarians from a Mediterranean population. METHODS: We analyzed the primary health records of all nonagenarians living in the Community of Madrid (N = 59,423) and collected data for 4 groups: Group 1, individuals without T2DM or established CVD (T2DM-, CVD-); Group 2, individuals without T2DM but with established CVD (T2DM-, CVD +); Group 3, individuals with T2DM but without established CVD (T2DM + , CVD-); and Group 4, individuals with both T2DM and established CVD (T2DM + , CVD +), taking into account the influence of sex on the outcomes. Follow-up was 2.5 years. The primary outcomes were cumulative incidence and incidence density rates for all-cause mortality, non-fatal myocardial infarction, non-fatal stroke (the first composite primary outcome [CPO1]), combined with heart failure (CPO2). We evaluated the adjusted effect of each group on all-cause mortality (Cox regression). RESULTS: Mean age was 93.3 ± 2.8 years (74.2% women). Hypertension, dyslipidemia, heart failure, albuminuria, and estimated glomerular filtration rate < 60 mL/min/1.73 m2 were significantly more prevalent in G4 than in the other groups (all p values < 0.001). We observed significantly higher cumulative incidence rates for all-cause mortality, CPO1, and CPO2 in participants belonging to G4 (all p values ≤ 0.001). People in G2 presented higher rates of all-cause mortality, heart failure, CPO1, and CPO2 than people in G3 (all p values ≤ 0.001). In the fully adjusted model, G4 independently predicted all-cause mortality (HR = 1.48 [95% CI, 1.40 to 1.57] vs reference G1 [p < 0.01]). In addition, significant HRs were recorded for cardiovascular disease alone (G2) and type 2 diabetes mellitus alone (G3) (1.13 and 1.14, respectively; both p values < 0.01). CONCLUSIONS: In Spanish nonagenarians, established cardiovascular disease and type 2 diabetes mellitus conferred a modest risk of all-cause mortality. However, the simultaneous presence of both conditions conferred the highest risk of all-cause mortality.

Cardiovascular risk factors associated with acute myocardial infarction and stroke in the MADIABETES cohort.

We aimed to develop two models to estimate first AMI and stroke/TIA, respectively, in type 2 diabetes mellitus patients, by applying backward elimination to the following variables: age, sex, duration of diabetes, smoking, BMI, and use of antihyperglycemic drugs, statins, and aspirin. As time-varying covariates, we analyzed blood pressure, albuminuria, lipid profile, HbA1c, retinopathy, neuropathy, and atrial fibrillation (only in stroke/TIA model). Both models were stratified by antihypertensive drugs. We evaluated 2980 patients (52.8% women; 67.3 ± 11.2 years) with 24,159 person-years of follow-up. We recorded 114 cases of AMI and 185 cases of stroke/TIA. The factors that were independently associated with first AMI were age (≥ 75 years vs. < 75 years) (p = 0.019), higher HbA1c (> 64 mmol/mol vs. < 53 mmol/mol) (p = 0.003), HDL-cholesterol (0.90-1.81 mmol/L vs. < 0.90 mmol/L) (p = 0.002), and diastolic blood pressure (65-85 mmHg vs. < 65 mmHg) (p < 0.001). The factors that were independently associated with first stroke/TIA were age (≥ 75 years vs. < 60 years) (p < 0.001), atrial fibrillation (first year after the diagnosis vs. more than one year) (p = 0.001), glomerular filtration rate (per each 15 mL/min/1.73 m2 decrease) (p < 0.001), total cholesterol (3.88-6.46 mmol/L vs. < 3.88 mmol/L) (p < 0.001), triglycerides (per each increment of 1.13 mmol/L) (p = 0.031), albuminuria (p < 0.001), neuropathy (p = 0.01), and retinopathy (p = 0.023).

Effect of depression on mortality in type 2 diabetes mellitus after 8 years of follow-up. The DIADEMA study.

AIM: To assess the effect of depression on all-cause mortality in patients with type 2 diabetes mellitus (T2DM) followed up during 8 years in primary care in Spain. METHODS: Depression was diagnosed according to MINI 5.0.0 questionnaire, physician-diagnosis or following antidepressant therapy for at least two months in 3923 people with T2DM. We analyzed mortality-rates/10,000 person-years. We compared survival according to baseline depression with Kaplan-Meier estimates and the log-rank test. We performed Cox proportional hazard model analyses. RESULTS: Baseline depression was diagnosed in 22.1% of participants. Mortality was higher in patients with depression (31.9% vs. 26.9%; p = 0.003), who had a significantly poorer survival (median survival = 7.4 vs. 7.8 years, respectively; Log Rank = 15.83; p < 0.001). Depression showed an adjusted mortality hazard ratio (HR) = 1.40 (95%CI:1.20-1.65; p < 0.001). The strongest predictive factors were: age >75 years (HR = 6.04; 95%CI:4.62-7.91; p < 0.001), insulin use (HR = 2.37; 95%CI:1.86-3.00; p < 0.001), lower limb amputation (HR = 1.99; 95%CI:1.28-3.11; p = 0.002), heart failure (HR = 1.94; 95%CI:1.63-2.30; p < 0.001), and male gender (HR = 1.90; 95%CI:1.59-2.27). CONCLUSION: In a Spanish cohort of older T2DM patients, depression was associated with a higher mortality risk. More efforts are needed to minimize the influence of depression on mortality in people with T2DM and to implement measures that allow its early diagnosis and effective treatment.

Prevalence of peripheral artery disease (PAD) and factors associated: An epidemiological analysis from the population-based Screening PRE-diabetes and type 2 DIAbetes (SPREDIA-2) study.

AIM: To describe the prevalence of Peripheral Artery Disease (PAD) in a random population sample and to evaluate its relationship with Mediterranean diet and with other potential cardiovascular risk factors such as serum uric acid and pulse pressure in individuals ranged 45 to 74 years. METHODS: Cross-sectional analysis of 1568 subjects (mean age 6.5 years, 43% males), randomly selected from the population. A fasting blood sample was obtained to determine glucose, lipids, and HbA1C levels. An oral glucose tolerance test was performed in non-diabetic subjects. PAD was evaluated by ankle-brachial index and/or having a prior diagnosis. RESULTS: PAD prevalence was 3.81% (95% CI, 2.97-4.87) for all participants. In men, PAD prevalence was significantly higher than in women [5.17% (95% CI, 3.74-7.11) vs. 2.78% (95% CI, 1.89-4.07); p = 0.014]. Serum uric acid in the upper quartile was associated with the highest odds ratio (OR) of PAD (for uric acid > 6.1 mg/dl, OR = 4.31; 95% CI, 1.49-12.44). The remaining variables more strongly associated with PAD were: Heart rate >90 bpm (OR = 4.16; 95%CI, 1.62-10.65), pulse pressure in the upper quartile (≥ 54 mmHg) (OR = 3.82; 95%CI, 1.50-9.71), adherence to Mediterranean diet (OR = 2.73; 95% CI, 1.48-5.04), and former smoker status (OR = 2.04; 95%CI, 1.00-4.16). CONCLUSIONS: Our results show the existence of a low prevalence of peripheral artery disease in a population aged 45-74 years. Serum uric acid, pulse pressure and heart rate >90 bpm were strongly associated with peripheral artery disease. The direct association between Mediterranean diet and peripheral artery disease that we have found should be evaluated through a follow-up study under clinical practice conditions.

Body mass index and all-cause mortality among type 2 diabetes mellitus patients: Findings from the 5-year follow-up of the MADIABETES cohort.

PURPOSE: To analyse the association between body mass index (BMI) and all-cause mortality in a 5-year follow-up study with Spanish type 2 diabetes mellitus (T2DM) patients, seeking gender differences. METHODS: 3443 T2DM outpatients were studied. At baseline and annually, patients were subjected to anamnesis, a physical examination, and biochemical tests. Data about demographic and clinical characteristics was also recorded, as was the treatment each patient had been prescribed. Mortality records were obtained from the Spanish National Institute of Statistics. Survival curves for BMI categories (Gehan-Wilcoxon test) and a multivariate Cox proportional hazard analysis were performed to identify adjusted Hazard Ratios (HRs) of mortality. RESULTS: Mortality rate was 26.38 cases per 1000patient-years (95% CI, 23.92-29.01), with higher rates in men (28.43 per 1000patient-years; 95% CI, 24.87-32.36) than in women (24.31 per 1000patient-years; 95% CI, 21.02-27.98) (p=0.079). Mortality rates according to BMI categories were: 56.7 (95% CI, 40.8-76.6), 28.4 (95% CI, 22.9-34.9), 24.8 (95% CI, 21.5-28.5), 21 (95% CI, 16.3-26.6) and 23.7 (95% CI, 14.3-37) per 1000person-years for participants with a BMI of <23, 23-26.8, 26.9-33.1, 33.2-39.4, and >39.4kg/m2, respectively. The BMI values associated with the highest all-cause mortality were <23kg/m2, but only in males [HR: 2.78 (95% CI, 1.72-4.49; p<0.001)], since in females this association was not significant [HR: 1.14 (95% CI, 0.64-2.04; p=0.666)] (reference category for BMI: 23.0-26.8kg/m2). Higher BMIs were not associated with higher mortality rates. CONCLUSIONS: In an outpatient T2DM Mediterranean population sample, low BMI predicted all-cause mortality only in males.

Incidence, surgical procedures, and outcomes of hip fracture among elderly type 2 diabetic and non-diabetic patients in Spain (2004-2013).

UNLABELLED: Hip fracture is a serious public health problem. We used Spanish hospital discharge data to examine trends in 2004-2013 in the incidence of hip fracture among elderly patients. We found that hip fracture incidence is higher in subjects with than without diabetes and is much higher among women than men. INTRODUCTION: This study aimed to describe trends in the incidence of hip fracture hospitalizations, use of surgical procedures, and hospital outcomes among elderly patients with and without type 2 diabetes mellitus (T2DM) in Spain, 2004-2013. METHODS: We selected all patients with a discharge primary diagnosis of hip fracture using the Spanish national hospital discharge database. Discharges were grouped by diabetes status: Incidences were calculated overall and stratified by diabetes status and year. We analyzed surgical procedures, length of hospital stay (LOHS), and in-hospital mortality (IHM). Multivariate analysis was adjusted by age, year, comorbidity, and in-hospital complications (IHC). RESULTS: From 2004 to 2013, 432,760 discharges with hip fracture were identified (21.3 % suffered T2DM). Incidence among diabetic men and women increased until year 2010 and then remained stable. Diabetic women have three times higher incidence than diabetic men. Incidences and IHC were higher among patients with diabetes beside sex. The proportion of patients that underwent internal fixation increased for all groups of patients and the arthroplasty repair decreased. After multivariate analysis, IHM has improved over the study period for all patients. Suffering diabetes was associated to higher IHM in women (odds ratio (OR) 1.12; 95 % confidence interval (CI) 1.07-1.17). CONCLUSIONS: Hip fracture incidence is higher in subjects with than without diabetes and is much higher among women than men. In diabetic patients, incidence rates increased initially but have leveled from 2010 onwards. For all groups, the use of internal fixation has increased overtime and IHM and LOHS have decreased from 2004 to 2013.

Trends in sepsis incidence and outcomes among people with or without type 2 diabetes mellitus in Spain (2008-2012).

AIMS: There is conflicting evidence on how type 2 diabetes mellitus (T2DM) influences in-hospital mortality (IHM) in sepsis. We aimed to compare trends in outcomes for sepsis in people with or without T2DM in Spain between 2008 and 2012. METHODS: We identified all cases with any sepsis diagnosis using national hospital discharge data. We evaluated annual incidence rates for sepsis stratified by T2DM status. We calculated IHM and analyzed trends over time. In a multivariate analysis including potential confounding factors, we tested T2DM as an independent factor for IHM. RESULTS: Overall, 217,280 cases of any-stage sepsis were diagnosed, of whom 50,611 (23.3%) had T2DM. The annual incidence of sepsis increased during the 5-year period (from 76.5 to 113.3cases/10(5) population). The incidence increase was higher for the population with T2DM (from 16.8 to 27.1 cases/10(5) population; 61.3% relative increment). People with T2DM were significantly older (75.8 ± 11.2 years vs. 71.0 ± 16.4 years) and suffered from more coexisting medical conditions. In the univariate analysis, mortality was higher for the population with T2DM only when septic shock was present (53.3% vs. 51.9%; P=0.002). IHM decreased over time both in participants with (from 45.7% to 38.1%) and without T2DM (from 46.1% to 39.5%). After accounting for all other potential confounders, T2DM was significantly associated with a lower IHM (odds ratio=0.88; 95% confidence interval, 0.86-0.90). CONCLUSIONS: In Spain, the annual increase in sepsis incidence was higher in people with T2DM, but the risk of dying with sepsis during admission was moderately lower in people with T2DM.
