AI Article Synopsis

  • A study tracked over 240,000 patients in Italy who were newly treated for hypertension to assess how sticking to their antihypertensive medications affected their heart health.
  • Results showed that those who consistently took their medications had a 37% lower risk of experiencing cardiovascular events compared to those who stopped treatment.
  • Higher adherence rates were linked to even more significant reductions in cardiovascular risk, highlighting the importance of maintaining medication compliance for preventing heart-related issues.

Article Abstract

Objective: The effect of compliance with antihypertensive medications on the risk of cardiovascular outcomes in a population without a known history of cardiovascular disease has been addressed by a large population-based prospective, cohort study carried out by linking Italian administrative databases.

Methods: The cohort of 242 594 patients aged 18 years or older, residents in the Italian Lombardy Region, who were newly treated for hypertension during 2000-2001, was followed from index prescription until 2007. During this period patients who experienced a hospitalization for coronary or cerebrovascular disease were identified (outcome). Exposure to antihypertensive drugs from index prescription until the date of hospitalization or censoring was assessed. Proportional hazards models were fitted to assess the association between persistence on and adherence with antihypertensive drug therapy and outcome. Data were adjusted for several covariates.

Results: During an average follow-up of 6 years, 12 016 members of the cohort experienced the outcome. Compared with patients who experienced at least one episode of treatment discontinuation, those who continued treatment had a 37% reduced risk of cardiovascular outcomes (95% confidence interval 34-40%). Compared with patients who had very low drug coverage (proportion of days covered ≤ 25%), those at intermediate (from 51 to 75%) and high coverage (>75%) had risk reductions of 20% (16-24%) and 25% (20-29%), respectively. Similar effects were observed when coronary and cerebrovascular events were considered separately.

Conclusions: In the real life setting, fulfillment compliance with antihypertensive medications is effective in the primary prevention of cardiovascular outcomes.

The effect of increased vascular afterload measures on flow rate and survival in severe aortic stenosis.

Eur Heart J Cardiovasc Imaging

January 2025

Faculty of Health and Medicine, Wallace Wurth Building (C27), Cnr High St & Botany St, UNSW Sydney, Kensington, NSW 2033, Australia.

Aims: Although an association between the systemic circulation and transaortic flow rate (TFR) is frequently hypothesized in patients with aortic stenosis (AS), it has not been demonstrated previously. We sought to explore the relationship between blood pressure (BP), vascular afterload measures, clinical history of hypertension, TFR, and survival in patients with severe AS (aortic valve area ≤ 1 cm²).

Methods And Results: We studied 323 patients ≥ 65 years (110 prospective, 213 registry analysis) who underwent transcatheter aortic valve replacement over a 5-year period.

Posterior reversible encephalopathy syndrome (PRES) is a clinical manifestation of various underlying causes, characterized by the combination of clinical and imaging findings associated with the posterior cerebral areas and relating to arterial hypertension and endothelial dysfunction. No association was made so far between PRES and McCune-Albright syndrome (MAS), a rare genetic disorder resulting in fibrous dysplasia. A 33-year-old female with MAS was presented to the emergency department of the 417 Army Share Fund Hospital in Athens (Greece) after seizure activity with two episodes of ocular upward deviation and transient facial palsy, each lasting a few minutes, followed by a postictal phase.

The prevalence of hypertension in Japan remains high, owing to the high salt content of the typical Japanese diet. Dairy-based foods may reduce blood pressure and hypertension risk. However, dairy consumption is low in Japan, and the relationships between dairy intake and blood pressure or the mechanisms by which dairy products affect blood pressure are not fully understood.

Introduction: Cardiovascular diseases represent the leading cause of mortality worldwide. This category includes cerebrovascular disease, ischemic heart disease, and peripheral vascular disease. Secondary prevention is effective for patients with a history of cardiovascular events, with antihypertensives, statins, and acetylsalicylic acid being the most prescribed drugs.

Objective More patients visit oral surgery outpatient clinics from evening to night to treat persistent gingival bleeding (PGB) related to periodontal disease (PD) (PD-PGB). Since there are few reports on PD-PGB, the present study performed a detailed characterisation of this disease. Materials and methods Patients who visited our oral surgery clinic between 1 January 2014 and 31 December 2022 to treat PD-PGB without trauma.
