Insights

Blood pressure control was achieved in 63.1% of patients, but only 38.4% adhered to antihypertensive drug therapy. Factors like male sex, low income, and stress impacted control and adherence.

Area of Science:

  • Cardiology
  • Public Health
  • Health Services Research

Background:

  • Limited data exists on blood pressure (BP) control and antihypertensive medication adherence in developing nations.
  • Understanding these factors is crucial for improving cardiovascular health outcomes.

Purpose of the Study:

  • To investigate factors associated with blood pressure control and medication adherence among hypertensive patients in Chile.
  • To identify key demographic, socioeconomic, and lifestyle predictors of treatment success.

Main Methods:

  • A cross-sectional study involving 992 hypertensive patients in a Chilean Cardiovascular Health Program.
  • Multivariate logistic regression analyzed associations between various factors (education, income, comorbidities, lifestyle, psychosocial status) and BP control/adherence.

Main Results:

  • Blood pressure control (<140/90 mmHg) was achieved in 63.1% of patients; 38.4% were adherent to therapy.
  • Uncontrolled BP linked to male sex, low income, high stress/depression, obesity, non-adherence, and sedentary lifestyle.
  • Non-adherence associated with male sex, low income, high stress/depression, low social support, and uncontrolled BP.

Conclusions:

  • Chilean hypertensive patients achieved BP control comparable to higher-income countries (63.1%).
  • Both uncontrolled BP and low medication adherence (38.4%) were significantly associated with male sex, socioeconomic status, and psychosocial factors.
  • Improved BP control and adherence were observed in diabetic patients.

Factors affecting Blood pressure

Several physiological and lifestyle factors influence blood pressure (BP). Understanding these factors is crucial as they are significant in patient education and blood pressure management.

Blood Pressure01:24

Blood Pressure

The movement of blood in a human body, commonly referred to as blood flow, is determined by the volume of blood that traverses a certain section of the bodily system per unit time. It is the rhythmic contraction of the heart's ventricles that primarily instigates this movement. As the ventricles contract, blood is forced into the prominent arteries, which then flow from areas of greater pressure to lower pressure areas. This movement continues into smaller arteries and arterioles and...

Blood Pressure01:30

Blood Pressure

Blood pressure (BP) is the pressure or force of blood exerted on the artery's walls as it circulates through the body. It is essential for maintaining blood flow throughout the body.
The average BP in an adult is typically around 120/80 mmHg (millimeters of mercury). In this measurement, the numerator (120) indicates the systolic pressure, which is the pressure in the arteries during the contraction of the heart's ventricles as blood is expelled. The denominator (80) represents the...

Measurement of Blood Pressure01:17

Measurement of Blood Pressure

Assessing blood pressure is a standard procedure executed in virtually all medical environments. The method utilized today was established over a hundred years ago by an innovative Russian doctor, Dr. Nikolai Korotkoff. The soft ticking noise, known as Korotkoff sounds, heard while taking blood pressure readings results from turbulent blood flow within the vessels. The apparatus required for this procedure includes a sphygmomanometer, a blood pressure cuff attached to a gauge, and a...

Alterations in Blood Pressure

Alterations in blood pressure, such as hypertension (high blood pressure) and hypotension (low blood pressure), significantly affect human health. Understanding these conditions' classifications, causes, and symptoms is essential for effective management and treatment.
Hypertension (High blood pressure)
Hypertension occurs when blood pressure readings consistently exceed the normal range. It is diagnosed when systolic blood pressure (the top number, indicating pressure while the heart...

Blood Studies for Cardiovascular System I: Cardiac Biomarkers

Cardiac biomarkers are enzymes, proteins, and hormones released into the blood when cardiac cells are injured. They are powerful tools for triaging.
The essential diagnostic tools for detecting myocardial necrosis and monitoring individuals suspected of having acute coronary syndrome (ACS) include:
Troponins
Troponins, particularly cardiac troponins I and T, are the most precise and sensitive markers of myocardial injury. They are detectable within 4-6 hours of myocardial injury and remain...
