Insights

Hypertension management in Thai stroke patients shows suboptimal blood pressure control, with less than half achieving targets. Inadequate antihypertensive use and poor patient awareness contribute to uncontrolled blood pressure in stroke survivors.

Area of Science:

  • Cardiovascular Medicine
  • Neurology
  • Public Health

Background:

  • Hypertension is a major risk factor for stroke mortality, necessitating strict blood pressure (BP) control.
  • Effective hypertension management in stroke patients is crucial for reducing secondary stroke events.

Purpose of the Study:

  • To determine the prevalence of controlled blood pressure (BP) in stroke patients in Thailand.
  • To evaluate current clinical practices for hypertension management among stroke patients.

Main Methods:

  • A multicenter, cross-sectional, retrospective, observational study.
  • Enrolled 558 stroke patients aged 45 years or older between February 2010 and January 2011.
  • Confirmed stroke events via CT scan or MRI; collected demographic, medical, and clinical history.

Main Results:

  • 49.1% of patients achieved controlled arterial BP (average 134.2/78.8 mm Hg) at enrollment.
  • 73.8% received antihypertensive medications, with Angiotensin-Converting Enzyme Inhibitors (ACEIs) being most common (35.8%).
  • Physicians cited insufficient antihypertensive use and lack of patient awareness as reasons for uncontrolled BP. Diabetes, hypertension stages, and ACEI use at discharge were associated with poorer BP control.

Conclusions:

  • A significant proportion of stroke patients in Thailand do not meet BP targets, despite evidence supporting BP control benefits.
  • Inadequate antihypertensive therapy and non-adherence to management guidelines likely contribute to poor BP control.
  • Improved hypertension management strategies are needed for stroke patients in Thailand to reduce secondary stroke risk.

Regulation of Stroke Volume01:27

Regulation of Stroke Volume

The regulation of stroke volume, which is the amount of blood the heart pumps out during each heartbeat, is critical for maintaining a healthy circulatory system. Stroke volume is influenced by three main factors: preload, contractility, and afterload.
Preload refers to the degree of stretch on the heart before it contracts. It's analogous to the stretching of a rubber band; the more it's stretched, the more forcefully it snaps back. This concept is encapsulated in the Frank-Starling law of the...

Errors occurring during blood pressure monitoring

Blood pressure monitoring is a crucial clinical procedure in diagnosing and managing various cardiovascular conditions. Despite its significance, the accuracy of blood pressure measurements can be compromised by multiple factors, potentially leading to either falsely high or low readings. These inaccuracies are critical as they can significantly impact patient care. So, it is vital to understand these challenges deeply and adopt strategic approaches to minimize errors.
Several factors...

Hypertension III: Clinical Manifestations and Diagnostic Studies

Hypertension is asymptomatic and also referred to as the "silent killer" until it progresses to a severe stage or causes target organ disease. Patients may experience symptoms stemming from the strain on blood vessels and tissues in various organs or the heart's increased workload.Physical exams might show no abnormalities other than high blood pressure. Signs of vascular damage, when present, correspond to the organs supplied by the affected vessels, leading to target organ damage. For...

Pre-Procedural Guidelines for Assessing Blood Pressure

Accurate blood pressure assessment is crucial for diagnosing and managing various health conditions. To ensure the reliability of these measurements, healthcare professionals must adhere to standardized pre-procedural guidelines. These guidelines enhance patient safety and improve the overall quality of healthcare. The following steps are essential for obtaining accurate and consistent blood pressure readings, from using the appropriate tools to ensuring effective communication with the patient.

Hypertension IV: Drug Therapy and Lifestyle Modifications

Multiple classes of antihypertensive medications are employed in treating hypertension. The most commonly recommended first-line treatments include:Thiazide Diuretics, such as chlorthalidone, increase sodium and water excretion from the body, reducing blood volume and blood pressure.Angiotensin-converting enzyme inhibitors, like lisinopril, block the conversion of angiotensin I to II, a potent vasoconstrictor lowering blood pressure.Angiotensin II Receptor Blockers (ARBs) prevent angiotensin II...
Hypertension and Regulation of Blood Pressure01:18

Hypertension and Regulation of Blood Pressure

Hypertension, the most common cardiovascular disease, is diagnosed through repeated measurements of elevated blood pressure. Its risks, including damage to the kidney, heart, and brain, are directly proportional to blood pressure levels. Starting from 115/75 mm Hg, the risk of cardiovascular disease doubles with each increment of 20/10 mm Hg. The diagnosis relies on blood pressure measurements, not on patient symptoms, as hypertension is often asymptomatic until end-organ damage is imminent or...
