Control of blood pressure and cardiovascular risk in Moroccan patients with newly diagnosed hypertension: a 3-month observational study in primary care.

BACKGROUND: Control of blood pressure and reduction of cardiovascular risk factors are mandatory in patients with hypertension. The aim of this study was to determine the proportion of patients with controlled hypertension and to describe the cardiovascular risk profile in hypertensive patients followed by general practitioners (GPs) in Morocco.

METHODS: This national, observational, multicentre, prospective, longitudinal study of patients with newly diagnosed hypertension was carried out between September 2011 and December 2011. The use of antihypertensive drugs was evaluated at inclusion and after 3 months of follow up. Uncontrolled hypertension was defined as systolic blood pressure (SBP) ⩾ 140 mmHg or diastolic blood pressure (DBP) ⩾ 90 mmHg at 3 months of follow up. The SCORE scale issued by the European Society of Cardiology (ESC) was used to assess overall cardiovascular risk and probability of experiencing a cardiovascular event within 10 years.

RESULTS: A total of 909 hypertensive patients were recruited (62.4% female). Mean age was 56.8 ± 10.6 years. More than half of the patients (53.0%) were between 40-60 years and more than one-third (34.1%) were obese [body mass index (BMI) ⩾ 30 kg/m2 ]. There were significantly more obese females than males ( p < 0.001). Over half of the patients (52.5%) had a high or extremely high cardiovascular risk. Abdominal obesity (measured as waist circumference) was the most common cardiovascular risk factor (61.7%) followed by age (40.5%), dyslipidaemia (36.3%) and diabetes (34.3%). Mean SBP decreased from 168.1 ± 14.8 to 138.3 ± 13.2 mmHg ( p < 0.001) and mean DBP decreased from 93.0 ± 10.5 to 81.0 ± 8.6 mmHg ( p < 0.001) after 3 months of treatment. Control of blood pressure was achieved in only 46.8% of patients. Poor compliance (17.1%) and a lack of treatment efficacy (16.9%) were the two main reasons for not achieving the blood pressure target.

CONCLUSIONS: More than half (53.2%) of the hypertensive patients in our study did not achieve adequate blood pressure control during the 3-month follow-up period and had a high cardiovascular risk. More effective management of hypertension is required in primary care.
