Insights

Embolic heart diseases cause 26% of ischemic strokes, with atrial fibrillation being the most common. Early cardiovascular checks are crucial for diagnosis and treatment, but access remains a challenge.

Area of Science:

  • Cardiology
  • Neurology
  • Public Health

Background:

  • Poor access to cardiovascular checkups leads to undiagnosed embolic heart diseases, a significant cause of ischemic stroke.
  • Identifying cardiac sources of embolism is critical for effective stroke management and prognosis.

Purpose of the Study:

  • To investigate ischemic strokes caused by embolic heart diseases.
  • To identify factors associated with embolic heart disease as a cause of ischemic stroke.

Main Methods:

  • A prospective, cross-sectional study of 104 ischemic stroke patients.
  • Data collected on socio-demographics, medical history, lifestyle, and specific embolic heart diseases (atrial fibrillation, myocardial infarction, etc.).
  • Statistical analysis using SAS 9.3.

Main Results:

  • Embolic heart diseases accounted for 26% of ischemic stroke etiologies.
  • Atrial fibrillation was the most frequent cause (69% of EHD, 22.8% of ischemic strokes).
  • Older age was significantly associated with embolic heart disease (p=0.000).

Conclusions:

  • Embolic heart disease is a prevalent cause of ischemic stroke, necessitating thorough cardiac evaluation.
  • Limited access to diagnostic tools like Holter ECG and cardiac ultrasound hinders timely diagnosis in many populations.

Ischemic Heart Disease: Overview01:17

Ischemic Heart Disease: Overview

Ischemic heart disease occurs when the heart's blood supply dwindles, causing an ominous lack of oxygen and nutrients. This deficiency, stemming from reduced or obstructed blood flow, spells danger, leading to heart muscle damage and dysfunction.
Atherosclerosis, the primary malefactor, orchestrates this dangerous condition. It manifests as the accumulation of fatty deposits, akin to insidious plaques, within arterial walls. As time elapses, these plaques metamorphose, hardening and...

Hospitals-II

Hospitals provide inpatient and outpatient services. Inpatient services provide care to patients that stay in the hospital for an extended period, ranging from days to months. Examples of inpatient services include intensive care units, hospital wards, or surgeries. Outpatient services provide care to patients who come to a hospital for a diagnostic or treatment but do not stay overnight —for example, diagnostic tests, surgical procedures, or health education.

Hospitals-I

Hospitals offer medical and surgical care to the sick and injured, along with accommodation while they recover. At the same time, they also provide outpatient, emergency, psychiatric, and rehabilitation services to meet various community needs. In addition to providing medical care, hospitals also act as hubs for medical research and training. Hospitals use clinical procedures and evidence-based practice standards to deliver patient care. To deliver safe and efficient care, a nurse must stay up...

Factors Influencing Heart Rate01:30

Factors Influencing Heart Rate

The heart rate, or pulse rate, is a vital indicator of cardiovascular health. It reflects the number of times the heart beats per minute. Various physiological and environmental factors influence heart rate, increasing or decreasing cardiac output. Understanding these factors is crucial for assessing heart function and identifying potential health issues.
Let us explore the significant factors affecting heart rate, including age, body temperature, posture, acute pain, chemical influences,...

Rheumatic Heart Disease I: Introduction

Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...

Pulmonary Embolism I: Introduction01:29

Pulmonary Embolism I: Introduction

Pulmonary embolism (PE) occurs when a thrombus, fat or air embolus, amniotic fluid, or tumor tissue blocks one or more pulmonary arteries. These blockages originate in the venous system or the right side of the heart.EtiologyPE primarily arises from deep vein thrombosis (DVT) and other hypercoagulable states, such as inherited thrombophilias. Additional etiological factors include venous stasis, commonly seen in obesity, and endothelial injury from surgery and trauma. Less common causes include...
