Insights

Carotid artery stenting (CAS) demonstrated a greater blood pressure (BP) reduction than carotid endarterectomy (CEA) at one year. CAS also resulted in more patients achieving normotensive BP levels post-procedure.

Area of Science:

  • Vascular Surgery
  • Cardiology
  • Interventional Neurology

Background:

  • Carotid artery stenosis poses a significant risk for stroke.
  • Carotid endarterectomy (CEA) and carotid artery stenting (CAS) are primary interventions for managing carotid artery stenosis.
  • The long-term impact of these procedures on blood pressure (BP) requires further investigation.

Purpose of the Study:

  • To compare the long-term effects of CEA and CAS on blood pressure (BP).
  • To evaluate BP reduction and normotensive rates following CEA versus CAS.

Main Methods:

  • A retrospective study included 102 patients (59 CEA, 43 CAS) with at least 1-year follow-up.
  • Patients were analyzed based on treatment group (CEA or CAS).
  • Percentage change in BP decrement and the proportion of normotensive patients were compared pre- and post-procedure.

Main Results:

  • Both CEA and CAS significantly reduced BP from baseline.
  • At 1-year follow-up, CAS showed a greater BP decrement (systolic: 9.6%, diastolic: 12.8%) compared to CEA (systolic: 5.9%, diastolic: 8.1%).
  • A higher percentage of patients achieved normotensive BP in the CAS group (46.5%) versus the CEA group (22.0%).

Conclusions:

  • Both carotid endarterectomy and carotid artery stenting exert beneficial BP-lowering effects.
  • Carotid artery stenting appears to offer superior blood pressure management compared to carotid endarterectomy at the 1-year mark.

Atherosclerosis III: Management01:26

Atherosclerosis III: Management

Management of atherosclerosis involves an integrated strategy encompassing pharmacological treatment, surgical interventions, lifestyle changes, and nutrition therapy to address the multifactorial nature of the disease.Pharmacological TherapyA cornerstone of atherosclerosis management is the use of pharmacological agents. Statins, such as atorvastatin, are pivotal in inhibiting HMG-CoA reductase, an enzyme that catalyzes an initial step in cholesterol synthesis in the liver. This reduction in...

Coronary Artery Disease V: Interprofessional Care

Interprofessional care for coronary artery disease includes pharmacological therapy and revascularization procedures.Pharmacological therapy for Coronary Artery Disease (CAD) aims to manage symptoms, prevent complications, and improve patient outcomes through various classes of medications:Antiplatelet Agents:Aspirin and Clopidogrel: These medications inhibit platelet aggregation, preventing blood clots, which is crucial for avoiding heart attacks and strokes. Doctors often prescribe these...

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...

Treatment for Pulmonary Arterial Hypertension: Receptor Tyrosine Kinase Inhibitors and Calcium Channel Blockers

Receptor tyrosine kinase inhibitors (TKIs) and calcium channel blockers (CCBs) are two critical categories of drugs employed in the treatment of pulmonary artery hypertension (PAH). PAH is a disease that causes high blood pressure in the pulmonary arteries, resulting in chest pain, fatigue, and shortness of breath.
TKIs, such as imatinib (Gleevec), are particularly effective in tackling the growth and mitogenic factors that become upregulated in PAH patients. These factors contribute to the...

Hypertension V: Nursing Management

The nursing management of hypertension involves accurately assessing symptoms, making a comprehensive nursing diagnosis, collaborating with patients to set goals, and implementing targeted interventions to mitigate the condition's impact and improve patient well-being.Comprehensive AssessmentThe initial step in nursing care for hypertension involves a thorough patient assessment. It includes evaluating symptoms such as headaches, dizziness, blurred vision, and previous hypertension episodes.

Assessment of blood pressure in brachial artery(two-step method)

Measuring blood pressure is a fundamental skill in healthcare that aids in diagnosing and monitoring hypertension and other cardiovascular conditions. An aneroid sphygmomanometer, commonly used in clinical settings, offers a manual and precise method for blood pressure measurement. The technique for using this instrument involves specific steps that must be carefully executed to ensure accuracy. The following detailed description outlines a two-step technique for assessing blood pressure using...
