In half of the patients admitted for observation for acute myocardial infarction, this diagnosis is disproved. Gastro-oesophageal reflux and/or disturbances of oesophageal motility are the cause of the thoracic pain resulting in hospitalization in 16-34% of these patients. In 13-59% of the patients with chronic recurrent thoracic pain without demonstrable ischaemic cardiac disease (IHD), oesophageal disease is, similarly, considered to be the cause of the pain. It is not possible to distinguish whether the pain is caused by oesophageal disease or IHD on the basis of the history, but the differential diagnosis is important as patients with pain on account of oesophageal disease have a good prognosis as regards mortality. The physical and mental conditions of the patients may be improved if the correct diagnosis is established and treatment instituted. Methods of examination to demonstrate oesophageal disease are described. On account of the frequency of the condition and the extent of the methods of examination, a programme of investigation is proposed for patients suspected of having thoracic pain due to oesophageal disease.

Apparent life-threatening event (ALTE) is a term used to define an event of unknown cause after an infant is found limp, cyanotic, bradycardic, and/or requires resuscitation. Eight to 15% of children with ALTE die of sudden infant death syndrome. Obstructive sleep apnea, bradycardia, gastroesophageal reflux, and laryngotracheal abnormalities are frequently associated with ALTE. Wide QT dispersion is associated with sudden death in heart failure and increased risk of ventricular fibrillation in acute myocardial infarction. Here, we assess QT dispersion in infants with ALTE and its correlation to clinical and electrocardiographic indices. The study included eighty nine infants (age 2.14 +/- 1.8 months, 46 males and 43 females) referred with ALTE to the pediatric emergency room and 18 controls (age 2.77 +/- 2.2 months) who underwent electrocardiogram assessment of QTmin, QTmax, QT dispersion (QT-D), and as well as QTmin, QTmax, and QT-D corrected for heart rate (QTcmin, QTcmax, QTC-D, respectively). All infants were referred at the usual diagnostic tests-the gastroesophageal reflux test, apnea monitoring, Holter ECG monitoring, electroencephalogram, and Doppler echocardiography. QT-D, QTc-D, and QTc-min were significantly greater in the ALTE group (p < 0.01). Greater QTc-D was found in males compared to females (p < 0.001). QT-D and QTc-D showed little or no correlation with age of infant or positivity of diagnostic tests. QTc has been found by multiple regression analysis to be the independent variable with the greatest impact on QTc-D (beta = -0.68, p < 0.001).

Chest pain is one of the most common symptoms driving patients to a physician's office or the hospital's emergency department. In approximately half of the cases, chest pain is of cardiac origin, either ischemic cardiac or nonischemic cardiac disease. The other half is due to noncardiac causes, primarily esophageal disorder. Pain from either origin may occur in the same patient. In addition, psychological and psychiatric factors play a significant role in the perception and severity of the chest pain, irrespective of its cause. Chest pain of ischemic cardiac disease is called angina pectoris. Stable angina may be the prelude of ischemic cardiac disease; and for this reason, it is essential to ensure a correct diagnosis. In most cases, further testing, such as exercise testing and angiography, should be considered. The more severe form of chest pain, unstable angina, also requires a firm diagnosis because it indicates severe coronary disease and is the earliest manifestation of acute myocardial infarction. Once a diagnosis of stable or unstable angina is established, and if a decision is made not to use invasive therapy, such as coronary bypass, percutaneous transluminal coronary angioplasty, or stent insertion, effective medical treatment of associated cardiac risk factors is a must. Acute myocardial infarction occurring after a diagnosis of angina greatly increases the risk of subsequent death. Chest pain in women warrants added attention because women underestimate their likelihood to have coronary heart disease. A factor that complicates the clinical assessment of patients with chest pain (both cardiac and noncardiac in origin) is the relatively common presence of psychological and psychiatric conditions such as depression or panic disorder. These factors have been found to cause or worsen chest pain; but unfortunately, they may not be easily detected. Noncardiac chest pain represents the remaining half of all cases of chest pain. Although there are a number of causes, gastroesophageal disorders are by far the most prevalent, especially gastroesophageal reflux disease. Fortunately, this disease can be diagnosed and treated effectively by proton-pump inhibitors. The other types of non-gastroesophageal reflux disease-related noncardiac chest pain are more difficult to diagnose and treat. In conclusion, the cause of chest pain must be accurately diagnosed; and treatment must be pursued according to the cause, especially if the cause is of cardiac origin.

Approximately 1 percent of primary care office visits are for chest pain, and 1.5 percent of these patients will have unstable angina or acute myocardial infarction. The initial goal in patients presenting with chest pain is to determine if the patient needs to be referred for further testing to rule in or out acute coronary syndrome and myocardial infarction. The physician should consider patient characteristics and risk factors to help determine initial risk. Twelve-lead electrocardiography is typically the test of choice when looking for ST segment changes, new-onset left bundle branch block, presence of Q waves, and new-onset T wave inversions. For persons in whom the suspicion for ischemia is lower, other diagnoses to consider include chest wall pain/costochondritis (localized pain reproducible by palpation), gastroesophageal reflux disease (burning retrosternal pain, acid regurgitation, and a sour or bitter taste in the mouth), and panic disorder/anxiety state. Other less common but important diagnostic considerations include pneumonia (fever, egophony, and dullness to percussion), heart failure, pulmonary embolism (consider using the Wells criteria), acute pericarditis, and acute thoracic aortic dissection (acute chest or back pain with a pulse differential in the upper extremities). Persons with a higher likelihood of acute coronary syndrome should be referred to the emergency department or hospital.
