In conclusion, 3-4 weeks of classical LHTH is sufficient to increase Hbmass but exerts no effect on swimming-specific VO2peak. LHTH may improve performance more than SL training.

Asymptomatic patients with newly diagnosed type 2 diabetes had plaque features associated with increased vulnerability as compared with age- and sex-matched controls.

We found a significant association between CRT measured as a continuous variable and short-term mortality. Using the definition of Schriger and Baraff also seems appropriate, but this is based on calculations of limited power.

In people with newly diagnosed Type 2 diabetes, women had lower absolute coronary plaque volumes but a more unfavourable plaque composition and enhanced systemic inflammation compared with men.

Purpose: To determine the occurrence of physiological significant coronary artery disease (CAD) by coronary CT angiography (CTA) derived fractional flow reserve (FFRCT) in asymptomatic patients with a new diagnosis (<1 year) of type-2 diabetes mellitus (T2DM). Methods: FFRCT-analysis was performed from standard acquired coronary CTA data sets. The per-patient minimum distal FFRCT-value (d-FFRCT) in coronary vessels (diameter ⩾1.8 mm) was registered. The threshold for categorizing FFRCT-analysis as abnormal was a d-FFRCT ⩽0.75. Total plaque volume and volumes of calcified plaque, non-calcified plaque, and low-density non-calcified plaque (LD-NCP) were assessed by quantitative plaque analysis. Results: Overall, 76 patients; age, mean (SD): 56 (11) years; males, n (%): 49(65), were studied. A total of 57% of patients had plaques. The d-FFRCT was ⩽0.75 in 12 (16%) patients. The d-FFRCT, median (IQR), was 0.84 (0.79–0.87). Median (range) d-FFRCT in patients with d-FFRCT ⩽0.75 was 0.70 (0.6–0.74). Patients with d-FFRCT⩽0.75 versus d-FFRCT >0.75 had numerically higher plaque volumes for all plaques components, although only significant for the LD-NCP component. Conclusion: Every sixth asymptomatic patient with a new diagnosis of T2DM has hemodynamic significant CAD as evaluated by FFRCT. Flow impairment by FFRCT was associated with coronary plaque characteristics.

Background Coronary CT angiography (CCTA) derived fractional flow reserve (FFRct) is increasingly for decision-making in patients with stable chest pain. The relation between vessel specific plaque characteristics and the translesional gradient by FFRct in patients with type-2 diabetes mellitus (T2DM) is not fully explored. Purpose To examine the association between vessel specific plaque characteristics as determined by CCTA and the translesional gradient as assessed by FFRct in asymptomatic patients with newly diagnosed T2DM. Methods Total plaque volume and the volumes of calcified plaque (CP), low-density noncalcified plaque (LD-NCP) and non-LD-NCP were assessed on a per-vessel basis by quantitative plaque analysis using Autoplaque. Irregularities of the vessel wall giving a vessel-specific total plaque volume <50 mm3 were excluded from the analyses. Positive remodeling was defined by a remodeling index >1.1. Spotty calcification was defined as calcifications comprising <90° of the vessel circumference and <3 mm length. FFRct-analysis was performed from standard acquired CCTA data sets by HeartFlow. Any FFRct-value in the major coronary arteries >1.8 mm in diameter was registered. The translesional gradient, defined as the difference of FFRct-values immediately proximal and distal to lesion, was calculated in most severe lesion per-vessel. Lesions were categorized according to a ΔFFRct threshold of 0.06. Plaque analysis and comparison to ΔFFRct were performed by staff blinded to patient data. Results A total of 76 patients; age, mean (SD): 56 (11) years; males, n (%): 49 (65), with newly diagnosed (<1 year) T2DM were studied. Haemoglobin A1c, median (IQR) was 45 mmol/L (42–50). Risk factors, mean (SD) were as follows: total-cholesterol, 4.4 mmol/L (1.0); LDL-cholesterol, 2.5 mmol/L (0.8); systolic blood pressure, 131 mmHg (12). In the analysis 57 vessels in 30 patients were included, while 24 vessels were classified as having irregularities. ΔFFRct ≥0.06 was registered in 22 (39%) plaques. Vessel specific plaque volumes (mm3), ΔFFRct ≥0.06 vs. ΔFFRct <0.06, were, median (IQR): LD-NCP, 28.1 (9.5–62.3) vs. 18.3 (10.2–27.5); non-LD-NCP, 129.5 (74.1–186.8) vs. 98.1 (65.7–142.1); total plaque volume, 209.4 (137.1–359.3) vs. 139.6 (108.3–220.0), all p>0.05. The vessel-specific CP volume, median (IQR), was higher in vessels with ΔFFRct ≥0.06 vs. ΔFFRct <0.06: 51.9 (20.5–85.4) vs. 13.5 (4.1–68.5), p=0.015. Adverse plaque characteristics ΔFFRct ≥0.06 vs. ΔFFRct <0.06, were, n (%): positive remodeling, 21 (95%) vs. 34 (97%) and spotty calcification, 9 (41%) vs. 14 (40%). The relative distribution of vessel specific plaque components according to ΔFFRct is illustrated in the Figure. Conclusion In asymptomatic patients with newly diagnosed and well-controlled T2DM, the occurrence of high-risk coronary plaque features was frequently observed. The applied translesional gradient by FFRct was not predictive of adverse coronary plaque characteristics.
