Blood pressure, antihypertensive treatment and factors associated with good blood pressure control in hypertensive diabetics: the Tarmidas study

Blood pressure control and its associated factors in patients with hypertension and type 2 diabetes

In this retrospective study, the medical records of hypertensive patients with type 2 diabetes attending two major hospitals were reviewed to find the factors associated with poor blood pressure control in patients who have diabetes as a comorbid disease with hypertension. Binary regression analysis was conducted to find the factors independently associated with BP control. A total of 522 participants were included in the study. Most of the participants had uncontrolled hypertension (63.4%) and uncontrolled type 2 diabetes (51.3%). Regression results revealed that having retinopathy (OR=1.468 (95% CI: 1.020-2.113), p<0.05), and not receiving dipeptidyl-peptidase 4 (DPP4) inhibitors were independently associated with uncontrolled BP (OR=0.633 (95%CI 0.423-0.946), p<0.05). Therefore, greater efforts should be exerted to improve BP control in hypertensive patients with type 2 diabetes, particularly in those suffering from retinopathy.

Blood pressure control in primary care patients with arterial hypertension: analysing the Hypertension Register data

Aim. (1) To investigate clinical characteristics of primary care patients with arterial hypertension (AH), according to the achievement of target blood pressure (BP) levels; (2) to assess the effectiveness of therapeutic measures aimed at achieving target BP and maintaining its long-term control. Material and methods. This retrospective analysis included the data from ambulatory medical records of 5558 AH patients, who attended primary care centres in 2007. Clinical characteristics were compared in patients with achieved vs. non-achieved target BP levels. According to the national AH guidelines (2004), the completeness of examination, pharmaceutical therapy tactics, and frequency of the follow-up were assessed in both groups. Results. Based on the 2007 data, target BP levels were maintained in 28% of AH patients. Mean BP level was 144/87 mm Hg. Patients with optimal BP levels, compared to their peers with inadequate BP control, had significantly (p<0,001) higher prevalence of angina pectoris (40,4% vs. 30,1%, respectively) or previous myocardial infarction (19,4% vs. 8,4%), as well as higher frequency of lipid profile assessment, creatinine measurement, and echocardiography. Mean number of prescribed antihypertensive medications was 2,08 vs. 1,60, respectively. Mean number of clinical visits per year was 4,07 vs. 2,99, while mean interval between the visits reached 72,3 vs. 62,7 days, respectively. Regardless of the target BP achievement, the quality of diagnostic and therapeutic management did not comply with the recommended standards. Conclusion. Patients with optimal BP control were characterised by a more severe clinical course, as well as by a wider scope and higher frequency of diagnostic and therapeutic procedures. At the primary care level, the quality of AH diagnostics and treatment did not comply with the recommended standards; therefore, mean BP levels in the AH Register sample were higher than the target ones.

[Evaluation and control of hypertensive diabetics seen in Primary Care centres in Spain. BRAND II study]

OBJECTIVE

We aimed to verify the level of blood pressure and glucose control and treatment in hypertensive diabetics seen in Primary Care Centres in Spain.

DESIGN

Descriptive study conducted on hypertensive diabetic patients who attended primary care centres for any reason.

LOCATION

Primary Care centres throughout Spain.

PARTICIPANTS

The study included 6,777 patients.

MEASUREMENTS

Blood pressure, weight, height, waist circumference, blood analysis and treatment were recorded

RESULTS

The mean age of the sample was 64.40 (11.50) years. Mean blood glucose was 141.8 (39) mg/dl, glycosylated haemoglobin was ≤7% in 45.9% of the sample, and blood pressure was under control (BP≤130/80 mmHg) in 9.8% of the patients studied. LDL Cholesterol was ≤100mg/dl in 25.3% of the sample. The drugs most used to control diabetes were; sulphonylureas 2259 patients (33.3%) and biguanides 3768 patients (55.6%). A total of 556 patients were on treatment with insulin, which represented 8.2% of the population studied. The drugs most used for hypertension were; diuretics in 3395 patients (50.1%) and angiotensin-converting enzyme inhibitors in 4053 patients (59.8%).

CONCLUSIONS

A large proportion of hypertensive diabetics are insufficiently controlled.
