Summary
Simultaneous upper gastrointestinal bleeding (UGIB) and myocardial injury occurred in 40.6% of patients. Liver cirrhosis and multiple cardiac risk factors predict this dangerous combination.
Area of Science:
- Cardiology
- Gastroenterology
- Emergency Medicine
Background:
- Upper gastrointestinal bleeding (UGIB) is a common emergency.
- Myocardial injury can complicate UGIB, impacting patient outcomes.
- Epidemiology and predictive factors for this dual condition require further investigation.
Purpose of the Study:
- To evaluate the incidence of simultaneous UGIB and myocardial injury.
- To identify predictive risk factors for developing myocardial injury during UGIB.
Main Methods:
- 155 patients with UGIB were assessed for myocardial injury using ECG and cardiac enzymes (Troponin I, CK-MB).
- Myocardial injury was defined based on specific ECG changes and enzyme levels.
- Risk factors were analyzed using univariate and multivariate approaches.
Main Results:
- 32.9% and 7.74% of patients experienced mild and moderate myocardial injury, respectively.
- Myocardial injury was significantly more common in variceal bleeding (80%) versus ulcer bleeding (20.5%).
- History of liver cirrhosis and >3 cardiac risk factors were key predictors of myocardial injury.
Conclusions:
- Simultaneous UGIB and myocardial injury is a significant clinical problem, particularly in variceal bleeding.
- Liver cirrhosis and multiple cardiac risk factors identify high-risk patients needing closer monitoring.
- Myocardial injury in UGIB patients is associated with longer hospital stays and increased transfusion needs.

01:24Esophageal Varices-I: Introduction
Esophageal varices are dilated, tortuous veins which are found mainly in the submucosa of the lower esophagus but which may also appear higher up or extend into the stomach. They develop due to increased pressure in the portal venous system, often as a result of liver cirrhosis. This condition scars and damages the liver, impeding normal blood flow through the portal vein. To compensate, blood seeks alternative pathways, forming fragile new vessels (varices) in the esophagus and stomach. These...
01:25Gastroesophageal Reflux Disease
Gastroesophageal reflux disease (GERD) is the backward flow of stomach contents (acid, pepsin, or bile) into the esophagus, causing mucosal inflammation known as esophagitis. It results from failure of antireflux mechanisms, mainly the lower esophageal sphincter (LES), influenced by mechanical and physiological factors.Etiology and Risk FactorsGERD develops when LES function is weakened or when intra-abdominal pressure increases. Risk factors include aging, obesity, and sliding hiatal hernia,...
01:30Acute 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...
01:30Peptic Ulcer Disease I: Introduction
Peptic Ulcer Disease (PUD) is characterized by mucosal excavation in the esophagus, stomach, pylorus, or duodenum. It can manifest as acute or chronic based on the extent and duration of mucosal involvement.
An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.
Peptic ulcers can also be...

01:25Peptic Ulcer Disease I: Introduction
Peptic ulcer disease (PUD) involves breaks in the gastrointestinal tract's mucosal lining, primarily in the stomach and duodenum, with less frequent occurrences in the lower esophagus or near the pylorus.Ulcers can be acute or chronic. Acute ulcers are short-lived with minimal inflammation and heal quickly after the irritant is removed. Chronic ulcers persist, may recur, and often cause scarring due to ongoing tissue damage. Superficial erosions affect only the mucosal layer and are called...
01:20Blood Studies for Cardiovascular System I: Cardiac Biomarkers
Cardiac biomarkers are enzymes, proteins, and hormones released into the blood when cardiac cells are injured. They are powerful tools for triaging.
The essential diagnostic tools for detecting myocardial necrosis and monitoring individuals suspected of having acute coronary syndrome (ACS) include:
Troponins
Troponins, particularly cardiac troponins I and T, are the most precise and sensitive markers of myocardial injury. They are detectable within 4-6 hours of myocardial injury and remain...
