Blood Pressure Reduction in the Primary and Secondary Prevention of Stroke

Assessment of medication adherence among Lebanese adult patients with non-communicable diseases during COVID-19 lockdown: a cross-sectional study

Background

Medical treatment is considered a cornerstone in non-communicable diseases (NCDs) management, lack of adherence remains the main challenge that may compromise optimal therapeutic outcome achievement.

Purpose

This study aimed to evaluate treatment adherence levels and associated factors among Lebanese adult patients with non-communicable diseases.

Materials and methods

A cross-sectional survey conducted during the COVID-19 lockdown imposed by the Lebanese Government (between September 2020 and January 2021) enrolled 263 adult patients through an anonymous online questionnaire to assess adherence to medications using the Lebanese Medication Adherence Scale (LMAS-14).

Results

Of the total sample, 50.2% showed low adherence with a total mean adherence score of 4.41 ± 3.94. The results showed that depression (β = 1.351) and peptic ulcer (β = 1.279) were significantly associated with higher LMAS scores (lower adherence). However, age between 50 and 70 (β = -1.591, p = 0.011), practicing physical exercise (β = -1.397, p = 0.006), having kidney disease (β = -1.701, p = 0.032), and an intermediate (β = -1.336, p = 0.006) to high income (β = -3.207, p < 0.001) were significantly associated with lower LMAS scores (higher adherence).

Conclusion

Our study shed light on the factors affecting medication adherence in patients with non-communicable diseases. It showed that depression and peptic ulcer were associated with lower adherence, contrary to older age, exercising, having chronic kidney disease, and a higher socioeconomic status.

Determinants of Stroke in a General Male Population

Background and Purpose—

To further improve preventive strategies against stroke, there is a need for epidemiological long-term studies. The study aimed at a prospective investigation of stroke determinants in the general male population.

Methods—

During a period of 48 years, from 50 to 98 years of age, a population-based sample of 854 men was followed using repeated medical examinations, lifestyle questionnaires, data from hospital records and the National Cause of Death Register.

Results—

Determinants of ischemic stroke were atrial fibrillation (hazard ratio [HR], 6.61; 95% CI, 4.47–9.77); mother dead from cardiovascular disease (HR, 1.53; 1.09–2.17); high education (HR, 0.81; 0.69–0.96); and high physical activity level during leisure time (HR, 0.68; 0.50–0.93). For hemorrhagic stroke heart rate (HR, 1.04; 1.01–1.06) and mother dead from stroke (HR, 3.56; 1.43–8.87) constituted an increased risk. Statistically significant determinants for all stroke were atrial fibrillation (HR, 5.34; 3.68–7.75); high diastolic blood pressure (HR, 1.02; 1.01–1.03); high body weight (HR, 0.96; 0.94–0.99); high educational level (HR, 0.79; 0.68–0.92); wide waist circumference (HR, 1.04; 1.01–1.07); smoking (HR, 1.25; 1.06–1.48); mother dead from cerebrovascular disease (HR, 1.43; 1.05–1.94); and diabetes mellitus (HR, 1.65; 1.02–2.68). Of all men diagnosed with atrial fibrillation, 88% had a stroke during follow-up.

Conclusions—

Atrial fibrillation was by far the strongest determinant of stroke during 48 years of follow-up in a male population sample followed until the age of 98 years. The results warrant improved prophylaxis through intense treatment of modifiable determinants.

Definition of Best Medical Treatment in Asymptomatic and Symptomatic Carotid Artery Stenosis

Implementation of best medical treatment (BMT) is the cornerstone of the management of patients with either asymptomatic or symptomatic carotid artery stenosis. We review the literature to define the components of BMT. Smoking cessation, maintaining a healthy body weight, moderate exercise, and a Mediterranean diet are essential lifestyle measures. Moderate alcohol consumption may also be beneficial but recommending it to patients may be hazardous if they consume too much. The importance of lifestyle measures is largely underestimated by both physicians and patients. Blood pressure and diabetes control, antiplatelet agents, and lipid-lowering treatment with statins/ezetimibe comprise the pharmacological components of BMT. Initiation of an intensive regimen of BMT is a sine qua non for patients with carotid artery stenosis whether or not they are offered or undergo an invasive revascularization procedure.

The management of hypertension for primary stroke prevention: a proposed approach

The prevalence of hypertension in society is high and increasing. Untreated hypertension results in stroke, dementia, and damage to major organs. This article reviews the risks that hypertension causes and the issues now generally accepted as playing a role in the low level of hypertension control. These include lack of public awareness of the significance of elevated blood pressure, lack of impetus to measure blood pressure, lack of sites to perform the measurements, occasional therapeutic inertia on the part of the medical community, and poor compliance with treatment on the part of affected individuals. Innovative measures that may result in improved management of this risk factor are discussed. These include ubiquitous blood pressure measurement sites, expanding therapeutic potential by involving allied health professionals, and offering rewards for treatment and for compliance. The article also emphasises that the ideal blood pressure target for the primary prevention of stroke remains unclear.
