Table 4 Definitions of significant improvement per risk factor

From: Cardiovascular disease prevention in rural Nigeria in the context of a community based health insurance scheme: QUality Improvement Cardiovascular care Kwara-I (QUICK-I)

Risk factor Significant improvement
Blood pressure Blood pressure at target level:
  Patients without diabetes or established cardiovascular disease (CVD): < 140 mmHg systolic and < 90 mmHg diastolic.
  Patients with diabetes, renal disease or establish CVD: < 130 mm Hg systolic and 80 mmHg diastolic.
  For those who do not reach target levels: blood pressure decrease of > 10% systolic or diastolic
Dyslipidemia Lipid profile at target level:
  Primary prevention: total cholesterol (TC) < 5.0 mmol/L and low density lipoprotein (LDL) cholesterol < 3.0 mmol/l.
  Secondary prevention: TC < 4.0 mmol/L and LDL cholesterol < 2.5 mmol/l.
  For those who do not reach target levels: reduction in total cholesterol ≥ 25% or LDL ≥ 30% (whichever is greater).
Diabetes Fasting plasma glucose < 7.0 mmol/l
  Random plasma glucose of < 12 mmol/l
Abdominal Obesity Reduction of waist circumference to ≤ 102 cm (M), ≤ 88 cm (F)
Left Ventricular Hypertrophy (LVH) Regression of LVH (electrocardiogram based) according to Sokolov-Lyon criteria [44]
Microalbuminuria Disappearance of microalbuminuria (< 30 mg/ml in spot morning urine)
Proteinuria Disappearance of proteinuria (negative quantitative dipstick)
Renal impairment Improvement in creatinine clearance to a new estimated glomerular filtration rate class [45] after treatment.
Smoking Quit smoking
