Acute Coronary Syndrome III: Diagnostic Studies

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...

Acute Coronary Syndrome I: Introduction

Acute Coronary Syndrome I: Introduction

Acute Coronary Syndrome (ACS) encompasses a spectrum of heart conditions caused by sudden obstruction of coronary arteries, typically resulting from the rupture of an atherosclerotic plaque and subsequent thrombus (blood clot) formation. This obstruction can lead to partial or complete blockage of blood flow, causing varying degrees of myocardial ischemia or infarction.ACS includes the following clinical entities:Unstable Angina (UA)Non-ST-Elevation Myocardial Infarction (NSTEMI)ST-Elevation...

Summary

This summary is machine-generated.

Centralized stroke services face challenges with stroke mimics, accounting for 24.2% of admissions. Understanding these non-stroke cases, like headache or seizure, is crucial for optimizing stroke unit efficiency.

Area of Science:

Neurology
Health Services Research

Background:

Centralization of stroke services is a recent trend in several countries.
Accurate diagnosis of acute stroke is challenging, leading to a significant number of stroke mimics admitted to stroke units.

Purpose of the Study:

To describe the characteristics of the stroke mimic patient group.
To assess the impact of stroke mimics on stroke services.

Main Methods:

Analysis of routine clinical data from 2,305 consecutive stroke unit admissions at St George's Hospital, London.
Categorization of 335 individual mimic codes into 17 groupings.
Identification of 555 stroke mimic diagnoses (24.2% of admissions).

Main Results:

72% of stroke mimics presented with at least one stroke risk factor.
Common mimic diagnoses included headache, seizure, and syncope; medically unexplained symptoms and decompensation of underlying conditions were also frequent.
Median length of stay for stroke mimics was 1 day, with dementia diagnosis and MRI requirement associated with longer stays.

Conclusions:

Stroke mimics represent a heterogeneous patient group with substantial impact on stroke services, despite initial assessments.
Co-location of stroke and acute neurology services may enhance efficiency during service reorganizations.
