A case of syncope after exertion due to sigmoid septum evaluated by exercise stress echocardiography.

Unlabelled: A sigmoid septum is associated with sharp angulation and aging of the aortic root; however, it does not affect the pressure gradient in the left ventricular outflow tract and is generally asymptomatic. This report describes a 73-year-old woman who presented with syncope after exertion. Echocardiography revealed that the cause was left ventricular outflow tract stenosis associated with a sigmoid septum; her symptoms improved with beta-blocker therapy.

Serum zinc concentration in patients with myocardial infarction: a retrospective study.

Background: Zinc regulates the oxidative stress and inflammatory signaling cascade and affects the development and deterioration of cardiovascular disease. We investigated the prognosis of developing heart failure in patients with myocardial infarction.

Methods: Patients with myocardial infarction (n = 243) were divided using the median value of zinc concentration on admission into low (< 66 µg/dL at admission, n = 111) and high zinc group (≥ 66 µg/dL at admission, n = 132).

Effect of constipation on readmission for heart failure in patients with acute heart failure.

Aims: Constipation is a common gastrointestinal disorder that is associated with a high cardiovascular event rate in the general population. Although constipation is common in patients with cardiovascular diseases, only a few studies have examined the relationship between constipation and the prognosis of patients with heart failure. This study aimed to evaluate the effects of constipation on the prognosis of patients with acute heart failure.

Higher Recurrence Rate of Acute Coronary Syndrome in Patients with Multiple-Time Myocardial Infarction.

The recurrence rate of acute coronary syndrome (ACS) in patients after first-time myocardial infarction (MI) is over ten times higher than in the general population. However, it is unclear whether patients with multiple-time MI have an even higher recurrence rate of MI. This study aimed to compare the recurrence rate in patients with multiple-time MI with the rate in patients after first-time MI.
