Patient Denial of Myocardial Infarction in the Prehospital Phase: Prevalence and Correlates

PubMed
Abstract

Insights

Most patients deny myocardial infarction (MI) before hospitalization, even with clear symptoms. This denial impacts how patients respond to symptoms and seek medical help, highlighting a critical gap in prehospital cardiac care.

Area of Science:

  • Cardiology
  • Psychology

Background:

  • Limited understanding exists regarding patient denial of myocardial infarction (MI) prior to hospital admission.
  • Investigating prehospital denial is crucial for improving timely medical intervention.

Purpose of the Study:

  • To determine the prevalence of MI denial in the prehospital phase.
  • To identify factors associated with MI denial in patients experiencing symptoms.

Main Methods:

  • Secondary analysis of 166 hospitalized MI patients with high symptom congruence.
  • Utilized Brief COPE Inventory, Response to Symptoms Questionnaire, and perceived risk assessment.
  • Defined prolonged prehospital delay as arrival at hospital ≥1 hour after symptom onset.

Main Results:

  • 77% of patients denied the possibility of MI despite high symptom congruence.
  • Higher denial was associated with nonsmoking, lower perceived MI risk, less anxiety, and concerns about seeking help.
  • Denial correlated with underestimating symptom severity, delaying help-seeking, and passive symptom response.

Conclusions:

  • Prehospital denial of MI is highly prevalent.
  • Denial is negatively associated with cognitive, emotional, and behavioral responses to MI symptoms.
  • Addressing denial may improve prehospital delay and patient outcomes.

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...

IntroductionThe management of Acute Coronary Syndrome (ACS) aims to minimize myocardial damage, preserve myocardial function, and prevent complications.Initial ManagementInpatient management involves continuous cardiac monitoring, preferably in an ICU, focusing on blood pressure, serum sodium, potassium, and creatinine levels, and urine output. Ongoing pharmacologic management is crucial for stabilizing the patient.Supplemental Oxygen: Administer supplemental oxygen if oxygen saturation is...

Acute Coronary Syndrome II: Pathophysiology and Clinical Manifestations

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...

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...

Coronary Artery Disease III: Clinical Manifestations

Coronary Artery Disease (CAD) is a primary health risk worldwide, leading to significant morbidity and mortality. The condition arises from the buildup of atherosclerotic plaques within the coronary arteries, resulting in diminished blood supply to the heart muscle.The clinical manifestations of CAD vary widely, from asymptomatic stages to severe, life-threatening conditions. Understanding these manifestations is crucial for early diagnosis and effective management.Angina Pectoris: The Warning...
