Abstract Background Cardiovascular disease is the most common comorbidity in type 1 diabetes (T1D). Current guidelines, however, do not include routine echocardiography or cardiac biomarkers in T1D. Objectives To investigate if echocardiography and NT-proBNP provide incremental prognostic information in individuals with T1D without heart disease and with preserved left ventricular ejection fraction (LVEF). Methods A prospective cohort of individuals with T1D without heart disease and with preserved LVEF (≥45%) from the outpatient clinic were included. Follow-up was performed through Danish national registers. The association between E/e', a marker of diastolic function, from echocardiography and NT-proBNP with major adverse cardiovascular events (MACE) was tested. MACE was defined as death from all-causes, acute coronary syndromes, cardiac revascularization, incident heart failure, or stroke. Additionally, the incremental prognostic value when adding E/e' and NT-proBNP to the clinical Steno T1D Risk Engine score (including age, sex, duration of diabetes, systolic blood pressure, LDL, HbA1c, presence of albuminuria (micro-or macroalbuminuria), eGFR, smoking status, and physical activity [low, medium, high]), was examined. Follow-up was 100% complete. Results Of 964 individuals (mean (SD)) age 49.7 (14.5) years, 51% men, HbA1c 66 (14) mmol/mol, BMI 25.6 (4.0) kg/m2, and diabetes duration 26.1 (14.5) years), 121 (12.6%) experienced MACE during 7.5 years of follow-up. In the full multivariable model, E/e' significantly and independently predicted MACE: (HR (95%)) E/'e <8 (n=639) vs. 8–12 (n=248): 2.00 (1.23; 3.25), p=0.005, E/'e <8 vs E/e'≥12 (n=77): 3.36 (1.8; 6.1), p<0.001. Also, NT-proBNP significantly predicted outcome: NT-proBNP <150 pg/ml (n=435) vs. 150–450 pg/ml (n=386): 1.52 (0.9; 2.5), p=0.11, NT-proBNP <150 pg/ml vs NT-proBNP >450 pg/ml (n=143): 2.78 (1.6; 4.9), p<0.001. Adding both (log)E/e' and (log)NT-proBNP to the Steno T1D Risk Engine score significantly and incrementally improved risk prediction: Harrell's C-index: Steno T1D Risk Engine (AUC 0.783 (0.747; 0.818)) vs. Steno T1D Risk Engine + (log)E/e' (AUC 0.805 (0.773; 0.837)): p<0.001 and Steno T1D Risk Engine + (log)E/e' + (log) NT-proBNP (AUC 0.816 (0.783; 0.848)): p=0.002. The risk of MACE by groups of E/e' and NT-proBNP is shown in the figure. Figure 1 Conclusion In individuals with T1D without heart disease and with preserved LVEF, E/e' and NT-proBNP significantly improved risk prediction of cardiovascular events beyond clinical risk factors alone. Echocardiography and NT-proBNP could have a role in clinical care.

Aim Heart disease is a common fatal diabetes-related complication. Early detection of patients at particular risk of heart disease is of prime importance. Soluble urokinase plasminogen activator receptor (suPAR) is a novel biomarker for development of cardiovascular disease. We investigate if suPAR is associated with early myocardial impairment assessed with advanced echocardiographic methods. Methods In an observational study on 318 patients with type 1 diabetes without known heart disease and with normal left ventricular ejection fraction (LVEF) (biplane LVEF >45%), we performed conventional, tissue Doppler and speckle tracking echocardiography, and measured plasma suPAR levels. Associations between myocardial function and suPAR levels were studied in adjusted models including significant covariates. Results Patients were 55±12 years (mean±s.d.) and 160 (50%) males. Median (interquartile range) suPAR was 3.4 (1.7) ng/mL and LVEF was 58±5%. suPAR levels were not associated with LVEF (P=0.11). In adjusted models, higher suPAR levels were independently associated with both impaired systolic function assessed with global longitudinal strain (GLS) and tissue velocity s′, and with impaired diastolic measures a′ and e′/a′ (all P=0.034). In multivariable analysis including cardiovascular risk factors and both systolic and diastolic measures (GLS and e′/a′), both remained independently associated with suPAR levels (P=0.012). Conclusions In patients with type 1 diabetes with normal LVEF and without known heart disease, suPAR is associated with early systolic and diastolic myocardial impairment. Our study implies that both suPAR and advanced echocardiography are useful diagnostic tools for identifying patients with diabetes at risk of future clinical heart disease, suited for intensified medical therapy.

Aims Patients with type 1 diabetes have a high risk of cardiovascular disease. Yet, the importance of routine assessment of myocardial function in patients with type 1 diabetes is not known. Thus, we examined the prognostic importance of NT-proBNP and E/e′, an echocardiographic measure of diastolic function, in type 1 diabetes patients with preserved left ventricular ejection fraction (LVEF) and without known heart disease. Methods and results Type 1 diabetes patients without known heart disease and LVEF ≥45% enrolled in the Thousand and 1 study were included and followed through nationwide registries. The risk of major cardiovascular events (MACE) and death associated with levels of NT-proBNP and E/e′ was examined. Of 960 patients, median follow-up of 6.3 years (Q1–Q3: 5.7–7.0), 121 (12%) experienced MACE and 51 (5%) died. Increased levels of both NT-proBNP and E/e′ were associated with worse outcomes (adjusted hazard ratios for MACE = 1.56 (1.23–1.98) and 4.29 (2.25–8.16) per Loge increase for NT-proBNP and E/e′, respectively). NT-proBNP and E/e′ combined significantly improved the discrimination power of the Steno T1D risk engine (MACE, C-index: 0.813 (0.779–0.847) vs 0.779 (0.742–0.816); P = 0.0001; All-cause mortality, C-index 0.855 (0.806–0.903) vs 0.828 (0.776–0.880); P = 0.03). Conclusion In patients with type 1 diabetes, preserved ejection fraction, and no known heart disease, NT-proBNP and E/e′ were associated with increased risk of MACE and all-cause mortality. The risks associated with NT-proBNP and E/e′ combined identified patients at remarkably high risk.

Tachycardiomyopathy (TCM) is an underestimated cause of reversible left ventricle dysfunction. The aim of this study was to identify the predictors of recurrence and incidence of major cardiovascular events in TCM patients without underlying structural heart disease (pure TCM). The prospective, observational study enrolled all consecutive pure TCM patients. The diagnosis was suspected in patients admitted for heart failure (HF) with a reduced ejection fraction and concomitant persistent arrhythmia. Pure TCM was confirmed after the clinical and echocardiographic recovery during follow-up. From 107 pure TCM patients (9% of all HF admission, the median follow-up 22.6 months), 17 recurred, 51 were hospitalized for cardiovascular reasons, two suffered from thromboembolic events and one died. The diagnosis of obstructive sleep apnoea syndrome (OSAS, hazard ratio (HR) 5.44), brain natriuretic peptide on admission (HR 1.01 for each pg/mL) and the heart rate at discharge (HR 1.05 for each bpm) were all independent predictors of TCM recurrence. The left ventricular ejection fraction at discharge (HR 0.96 for each%) and the heart rate at discharge (HR 1.02 for each bpm) resulted as independent predictors of cardiovascular-related hospitalization. Pure TCM is more common than previously thought and associated with a good long-term survival but recurrences and hospitalizations are frequent. Reversing OSAS and controlling the heart rate could prevent TCM-related complications.

Early prediction of myocarditis clinical course still remains one of the actual tasks of cardiological science, which has a significant practical value. The purpose of the study was to determine the predictors of unfavorable course of myocarditis with reduced ejection fraction (EF) of the left ventricle (LV) on the basis of follow-up during 24 months. The study included 90 patients with acute myocarditis and reduced LV EF, who were examined in the first month after the disease onset, after 6, 12 and 24 months of follow-up. All patients underwent for echocardiography, Holter monitoring of the electrocardiogram and cardiac magnetic resonance imaging. Statistical processing of the results was performed using the Excel XP software (Місrosoft Office, USA) and Statistica for Windows v. 6.0 (Statsoft, USA). It was found that restoration of cardiac contractility in patients with myocarditis and reduced LV EF began with an increase in the index of LV longitudinal global systolic strain, which occurred 6 months after the debut of the disease and was associated with a decrease in the number of LV segments affected by the inflammatory process, and a significant increase of LV EF and a decrease of LV end-diastolic volume were observed only 1 year after the disease onset. The predictors of cardiovascular events in patients with acute myocarditis during the next 24 months from the onset of the disease, were detected in the 1st month from the debut of the disease and included following pathological changes: value of the LV EF ≤ 30%; reduction of LV longitudinal global systolic strain ≤ 7.0%; evidence of non-sustained ventricular tachycardia, presence of inflammatory changes in ≥6 LV segments, presence of delayed enhancement in ≥ 5 LV segments. Prospects for further research are the creation of registries of patients with myocarditis on the basis of multicenter clinical trial results on a large number of patients surveyed in order to improve diagnosis, prediction of clinical course and identification of early diagnostic markers of cardiovascular events and quantitative risk assessment of their development.

Exercise Ecg

21 patients with LAD-stenoses of at least 70% and 21 patients with LAD- stenoses and additional intramural anterior wall infarctions were studied. 20 patients without heart disease or after successful transluminal coronary angioplasty and 18 patients with intramural anterior wall infarction after successful transluminal dilatation of the LAD (remaining stenosis maximal 30%) served as controls. The normal range of global and regional left ventricular ejection fraction response to exercise was defined based on the data of 25 further patients without relevant coronary heart disease. Thus, a decrease in global ejection fraction and regional wall motion abnormalities were judged pathological. All patients were comparable with respect to age, ejection fraction at rest and work load. Myocardial ischemia could be detected by the exercise ECG in 81 % of all patients without infarction and in 71 % of patients with infarction. The corresponding values for global left ventricular ejection fraction were 76% and 81 %, respectively, and for regional ejection fraction 95% in both groups. No false-positive exercise ECGs were observed in the healthy controls and 2 (11 %) in the corresponding group with intramural infarction. The global ejection fraction was pathological in 1 (5%) healthy subject without infarction and in 3 (17%) corresponding patients with infarction. Sectorial analysis revealed 5 and 22%, respectively. Our findings suggest that the exercise ECG has a limited sensitivity to detect myocardial ischemia in patients with isolated LAD-stenoses and intramural myocardial infarction. Radionuclide ventriculography yields pathological values more often; however, false-positive results also occur more frequently.

Type 1 Diabetic Patients

Insulin-induced hypoglycemia occurs commonly in intensively treated patients with type 1 diabetes, but the cardiovascular consequences of hypoglycemia in these patients are not known. We studied left ventricular systolic [left ventricular ejection fraction (LVEF)] and diastolic [peak filling rate (PFR)] function by equilibrium radionuclide angiography during insulin infusion (12 pmol · kg−1 · min−1) under either hypoglycemic (∼2.8 mmol/l) or euglycemic (∼5 mmol/l) conditions in intensively treated patients with type 1 diabetes and healthy nondiabetic subjects ( n = 9 for each). During hypoglycemic hyperinsulinemia, there were significant increases in LVEF (ΔLVEF = 11 ± 2%) and PFR [ΔPFR = 0.88 ± 0.18 end diastolic volume (EDV)/s] in diabetic subjects as well as in the nondiabetic group (ΔLVEF = 13 ± 2%; ΔPFR = 0.79 ± 0.17 EDV/s). The increases in LVEF and PFR were comparable overall but occurred earlier in the nondiabetic group. A blunted increase in plasma catecholamine, cortisol, and glucagon concentrations occurred in response to hypoglycemia in the diabetic subjects. During euglycemic hyperinsulinemia, LVEF also increased in both the diabetic (ΔLVEF = 7 ± 1%) and nondiabetic (ΔLVEF = 4 ± 2%) groups, but PFR increased only in the diabetic group. In the comparison of the responses to hypoglycemic and euglycemic hyperinsulinemia, only the nondiabetic group had greater augmentation of LVEF, PFR, and cardiac output in the hypoglycemic study ( P < 0.05 for each). Thus intensively treated type 1 diabetic patients demonstrate delayed augmentation of ventricular function during moderate insulin-induced hypoglycemia. Although diabetic subjects have a more pronounced cardiac response to hyperinsulinemia per se than nondiabetic subjects, their response to hypoglycemia is blunted.
