The aim of this present prospective study was to investigate the accuracy of cardiac markers for the prediction of subsequent cardiac events (cardiac death, acute myocardial infarction and recurrent ischemia requiring coronary revascularization). ⋯ Changes in cut-off levels of cardiac markers and inflammatory parameters results in a high accuracy of risk stratification in patients with chest pains. Combination of these measurements might further help in the identification of patients who would benefit from early coronary revascularization.

Exertional dyspnea is a frequent limiting symptom in patients with chronic heart failure. Furthermore, dyspnea and a plateau in VO(2) (oxygen consumption) at peak exercise often co-exist in chronic heart failure, especially in patients with severe regurgitant valvular heart disease (RVHD), their relevance to hemodynamics and subjective symptoms during exercise have not been fully understood. ⋯ Development of pulmonary hypertension during exercise is the important limiting factor for exercise capacity in patients with RVHD. The limitation of increase in CO concomitant with pulmonary hypertension could be an important factor in the appearance of dyspnea.

Comparative Study
Minor myocardial damage detected by troponin T is a powerful predictor of long-term prognosis in patients with acute decompensated heart failure.
The progression of chronic heart failure (CHF) is characterized by frequent exacerbation requiring hospitalization and high mortality. Clinical deterioration is triggered by many factors that could promote ongoing myocytes injury. We sought to determine whether a specific marker of cardiac injury, troponin T (cTnT), is associated with prognosis in acute decompensated heart failure (ADHF). ⋯ One third of patients with decompensated CHF had elevated levels of cTnT. Troponin T was an independent long-term prognostic marker of morbidity and mortality and it suggests a role of biochemical risk stratification in this setting.

Intracranial aneurysms, coronary aneurysms and descending aortic coarctation--unreported association.
Rare association of coronary artery aneurysms with intra cranial aneurysms is reported. Also, association of abdominal aortic coarctation with intracranial aneurysms is rare. ⋯ On evaluation, she was found to have intracranial aneurysms in the vertebral and basilar artery, coronary aneurysms and descending thoracic aortic coarctation. This association is unreported.

Comparative Study
Cardiac troponin I release in acute pulmonary embolism in relation to the duration of symptoms.
To evaluate the release of cardiac troponin I in normotensive patients with acute pulmonary embolism in relation to the duration of symptoms. ⋯ The dynamics of cardiac troponin I release in acute pulmonary embolism in patients who present with symptoms of < or =72 h duration could be different from those who present with longer duration of symptoms. Therefore, the use of cardiac troponin I in risk stratification of acute pulmonary embolism might be limited to the patients presenting within 72 h of the onset of symptoms.
