Acute Coronary Syndrome III: Diagnostic Studies

409
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

1.5K
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...

High-Performance Liquid Chromatography: Introduction

4.0K
High-performance liquid chromatography(HPLC), formerly referred to as High-pressure liquid chromatography, is a powerful technique used to separate, identify, and quantify components in complex mixtures. The term "high pressure" refers to using high pressure to push the liquid mobile phase through the tightly packed columns.
In HPLC, two phases play a critical role in the separation process:

Nursing Assessment:Nursing management of acute coronary syndrome (ACS) involves taking the patient's history, focusing on primary complaints such as chest pain, dyspnea, and excessive sweating (diaphoresis), as well as other symptoms like back or jaw pain, nausea, vomiting, palpitations, dizziness, and fatigue. The nurse also reviews the patient's history of cardiac events, risk factors such as hypertension, diabetes, smoking, family history, and current medications.In the objective assessment,...

Acute Coronary Syndrome II: Pathophysiology and Clinical Manifestations

684
The pathophysiology of Acute Coronary Syndrome [ACD] involves several key processes:The main underlying cause of ACD is atherosclerosis, a chronic inflammatory disease characterized by the buildup of lipid-laden plaques within the coronary arteries.As the atherosclerotic plaque grows in the coronary artery, it may become unstable due to the formation of a lipid-rich core and a thin fibrous cap. Inflammatory cells within the plaque, such as macrophages, secrete enzymes that degrade the...

High-Performance Liquid Chromatography: Instrumentation00:57

High-Performance Liquid Chromatography: Instrumentation

3.5K
High-performance liquid chromatography, or HPLC, is an analytical technique that separates liquid samples under high pressures. An HPLC instrument consists of glass bottles for storing solvents called mobile phase reservoirs. HPLC-grade solvents are used to maintain high purity, and the dissolved gases are removed using a degasser, such as a vacuum pumping system or sparging with helium. The solvents are then pumped into the analytical column using a screw-driven syringe or reciprocating pumps.

Summary

This study reveals prolonged pre-hospital delay and low reperfusion rates in acute coronary syndrome (ACS) patients, leading to higher in-hospital mortality. Improving emergency response is crucial for ACS patient outcomes.

Area of Science:

  • Cardiovascular Medicine
  • Public Health
  • Clinical Research

Background:

  • Limited population-representative data on acute coronary syndrome (ACS) patient characteristics, treatment, and outcomes.
  • Need for comprehensive data to inform clinical practice and public health strategies for ACS.

Purpose of the Study:

  • To report on the clinical characteristics, treatment, and in-hospital outcomes of a large cohort of ACS patients.
  • To identify factors contributing to adverse outcomes in ACS.

Main Methods:

  • Analysis of data from 5180 ACS patients registered in a multicenter ACS Registry (2012-2014).
  • Standard diagnostic criteria used for ACS.
  • Evaluation of pre-hospital delay, reperfusion therapy, evidence-based treatment, and in-hospital mortality.

Main Results:

  • Majority of patients were male (70.8%), with a mean age of 60.9 years.
  • Non-ST-elevation myocardial infarction (NSTEMI) was more common than ST-elevation myocardial infarction (STEMI).
  • Long pre-hospital delay (median 780 min) and lower use of reperfusion therapy were observed, particularly in STEMI patients.
  • In-hospital mortality was 7.6%, significantly higher in STEMI (10.8%) than NSTEMI (5.0%).

Conclusions:

  • Significant pre-hospital delays and suboptimal reperfusion therapy use impact ACS patient outcomes.
  • Higher in-hospital mortality rates underscore the need for improved emergency medical services and timely interventions for ACS.
  • Evidence-based treatments were widely used, but outcomes suggest challenges in acute management and transport.
