Abstract Background Glycemic control, even in non-diabetes mellitus (DM) patients, has been associated with ventilation pump inefficiency leading to an impaired aerobic capacity. Brain natriuretic peptide (BNP) levels have also been correlated with exercise capacity, particularly in patients with heart failure. Purpose Assess the complementary impact of glycated haemoglobin (HbA1c) and BNP levels on cardiopulmonary exercise capacity in patients with ischemic heart disease (IHD). Methods Retrospecive cohort of 91 consecutive patients (57±10 years, 90% men; 29% type 2 DM) who underwent a cardiopulmonary exercise testing (CPX) at the beginning of an standard phase-II cardiac rehabilitation program, 2–3 months after an acute coronary syndrome. Results HbA1c and BNP levels correlated with peak oxygen uptake (VO2), anaerobic threshold (AT) and pulse O2 trajectory (Table). HbA1c correlated with ventilation CPX parameters (Table) and independently predicted minute ventilation (VE) and tidal volume (VT), regardless of age, waist circumference and β-blocker therapy. BNP levels correlated with echocardiographic (LVEF, left atrium size and pulmonary artery systolic pressure) and ventilation-perfusion (V/Q) mismatch parameters (Table), and independently predicted VE/VCO2-slope (P=0.037) regardless of age, echocardiographic parameters and β-blocker therapy. Patients were divided into three groups according to HbA1c levels above or below the DM diagnosis cut-off point (6.5%) and median value of BNP levels (44.6 pg/mL). VO2 and AT significantly decreased with elevated HbA1c and/or BNP levels (Figure). CPX parameters HbA1c (%) BNP (pg/mL) r P value r P value Peak VO2 (mL/min/kg) −0.421 <0.001 −0.295 0.005 VO2 at AT (mL/min/kg) −0.352 0.001 −0.271 0.009 O2 pulse trajectory (mL/beat) −0.345 0.001 −0.235 0.025 Minute ventilation (VE) (L/min)* −0.377 <0.001 – NS Tidal volume (VT) (L)* −0.348 0.001 – NS VE/VCO2-slope – NS 0.375 <0.001 PETCO2 at AT (mmHg) – NS −0.315 0.002 HR/VO2-slope – NS 0.307 0.003 *At peak exercise. NS: Non-significant. Conclusions HbA1c and BNP levels were associated with a reduced cardiopulmonary capacity in IHD patients, mediated by a ventilation impairment and a ventilation-perfusion mismatching, respectively. HbA1c and BNP are independent and additive predictors of cardiopulmonary capacity.

This study addresses the prevalence of ischemic heart disease, hypertension and long-term complications of diabetes mellitus among patients attending the diabetic clinic and their relation to glycemic control. Methods: A study was conducted on a cross-section on all consecutive patients attending the diabetic clinic at King Khalid National Guard Hospital in Jeddah, Saudi Arabia, from January 2007 to January 2008. The degree of glycemic control was gauged using blood level of glycosylated hemoglobin (HbA1C) and classified into good (less 7%), fair (7.1-8%), poor (8.1-9%) and very poor (greater than 9%). All patients were screened for hypertension, ischemic heart disease and microvascular complications. Results: Two hundred and ten patients were recruited in the study. Glycemic control was good in 17 (8.1%), fair in 49 (23.2%), poor in 56 (26.6%) and very poor in 88 (41.9%). There was high prevalence of retinopathy (76; 36%), microalbuminuria (80; 37.9%), neuropathy (108; 51.2%) and ischemic heart disease (51; 24.2%), especially among patients with poor and very poor control. Although the presence of hypertension, frank nephropathy and peripheral vascular disease was also disturbingly high among diabetic patients, their frequency was the same among good, fair, poor and very poor glycemic control groups. Conclusion: The prevalence of long-term complications of diabetes mellitus was alarmingly high among Saudi nationals. Microvascular complications and ischemic heart disease were also noticed to be more common in diabetics with poor and very poor glycemic control. This emphasizes the need of national awareness program about the gravity of the problem.
