Differences Between Gastroesophageal Reflux Disease and Coronary Heart Disease

Many people often confuse gastroesophageal reflux disease (GERD) with coronary heart disease due to similar symptoms such as chest discomfort. However, these two conditions differ significantly in terms of causes, symptoms, and treatment approaches.

Pain Location

Coronary heart disease typically causes pain on the left side of the chest, often radiating to the left arm, shoulder, or jaw. In contrast, GERD-related discomfort is usually felt behind the breastbone, along the central part of the chest.

Duration of Pain

Chest pain caused by coronary heart disease tends to last only a few minutes, usually not exceeding ten to fifteen minutes. On the other hand, GERD symptoms can persist for 30 minutes to an hour or even longer, especially after meals or when lying down.

Underlying Medical Conditions

Patients with coronary heart disease often have a history of cardiovascular issues such as hypertension, atherosclerosis, or high cholesterol. GERD, however, is more commonly associated with chronic gastrointestinal conditions, including hiatal hernia or delayed stomach emptying.

Relief Methods

Angina or chest pain from coronary heart disease can often be relieved with nitroglycerin, which helps dilate blood vessels. GERD symptoms, however, respond better to acid-reducing medications such as proton pump inhibitors (PPIs) or H2 blockers, which lower stomach acidity and reduce irritation in the esophagus.

Why Accurate Diagnosis Matters

Accurate differentiation between these two conditions is crucial for effective treatment. Misdiagnosis can lead to unnecessary medication use or delay in receiving appropriate care. If chest pain persists or recurs frequently, it is strongly recommended to consult a healthcare professional for a comprehensive evaluation, including possible ECG or endoscopic tests.
