title: Left ventricular hypertrophy in normoalbuminuric type 2 diabetic patients not taking antihypertensive treatment.
abstract: BACKGROUND
  Left ventricular hypertrophy (LVH) is an independent risk factor for myocardial ischaemia, cardiac arrhythmia, sudden death, and heart failure, all common findings in patients with type 2 diabetes.
  
  
  OBJECTIVE
  To determine the prevalence of, and risk factors for, LVH in normoalbuminuric type 2 diabetic patients not taking antihypertensive treatment.
  
  
  METHODS
  Cross-sectional study.
  
  
  METHODS
  From 1994 to 1998, M-mode echocardiography was performed by one experienced examiner in 262 consecutive, normoalbuminuric Caucasian type 2 diabetic patients, all with blood pressure <160/95 mmHg and not taking antihypertensive medication. Mean +/- SD age was 54 +/- 10 years, 109 were women, and median known duration of diabetes was 4 (range 1-28) years. Body mass index (BMI) was 28 +/- 5 kg/m(2), and blood pressure 134 +/- 13/79 +/- 8 mmHg, all means +/- SD. Median urinary albumin excretion rate was 9 (range 2-30) mg/24 h.
  
  
  RESULTS
  The prevalence of LVH indexed to height(2.7) was 43% (95%CI 38-50%), and was similar in men and women. BMI, HbA(1c) and log urinary albumin excretion were significantly associated with left ventricular hypertrophy in a logistic regression model, whereas sex, age, known duration of diabetes and blood pressure were not. Similar results were obtained for left ventricular mass index.
  
  
  CONCLUSIONS
  LVH was frequent in our normoalbuminuric type 2 diabetic patients not taking antihypertensive treatment. Several potentially modifiable risk factors, such as raised BMI, poor glycaemic control and elevated urinary albumin excretion rate, were associated with LVH.
