Insights

Lacunar stroke (LS) is common, affecting 35.5% of ischemic stroke patients. LS patients had lower admission severity scores and shorter hospital stays, indicating better short-term outcomes.

Area of Science:

  • Neurology
  • Cardiovascular Research
  • Public Health

Background:

  • Lacunar stroke (LS) accounts for 25% of ischemic strokes, causing significant long-term health and economic burdens.
  • Understanding the characteristics and outcomes of LS compared to other ischemic stroke subtypes is crucial for effective management.

Purpose of the Study:

  • To investigate and compare lacunar strokes (LS) with non-lacunar ischemic strokes.
  • To identify predictors and short-term outcomes of LS in a tertiary academic center.

Main Methods:

  • Retrospective review of 989 ischemic stroke patients admitted between February 2016 and July 2019.
  • Comparison of LS patients with other TOAST subtypes, excluding hemorrhagic stroke and stroke mimics.
  • Regression analysis to determine LS predictors and outcomes.

Main Results:

  • Lacunar stroke (LS) constituted 35.5% of all ischemic strokes in the cohort, with a majority of patients being male (71.9%).
  • Lower National Institutes of Health Stroke Scale (NIHSS) scores on admission and a lack of cardiac disease history were identified as predictors for LS.
  • LS patients exhibited lower NIHSS scores at discharge and shorter hospitalization durations compared to non-LS patients.

Conclusions:

  • Lacunar stroke (LS) is a prevalent subtype of ischemic stroke within this patient cohort.
  • LS is associated with less severe initial presentation and shorter hospital stays.
  • Further research with extended follow-up is necessary to fully understand stroke recurrence, complications, and long-term outcomes for LS patients.

Aneurysm II: Clinical Manifestations and Diagnostic Studies

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

Acute Coronary Syndrome III: Diagnostic Studies

Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...

Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies

The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...
