Perforated mitral valve aneurysm associated with Libman-Sacks endocarditis.

The perforation of a mitral valve aneurysm is a rare disease which induces acute mitral regurgitation and is usually induced by infective endocarditis; however, in this case report, acute heart failure was caused by a perforated mitral valve aneurysm that was speculated to be due to Libman-Sacks endocarditis with systemic lupus erythematosis and secondary anti-phospholipid syndrome. Mitral valve plasty was performed and thereafter heart failure improved.

The factors contributing to whether or not hypertensive patients bring their home blood pressure record to the outpatient clinic.

Objective: We investigated the factors contributing to whether or not hypertensive patients brought their home blood pressure records to the outpatient clinic.

Method: We studied 325 hypertensive patients [169 men (66.3+/-11.

The association between morning hypertension and metabolic syndrome in hypertensive patients.

Morning hypertension (MHT) and metabolic syndrome (MS) have been reported as important risk factors for stroke and cardiovascular events. We investigated the prevalence of MHT and MS among hypertensive patients in our outpatient clinic from June to August, 2005. We studied 181 hypertensive patients (91 men and 90 women) in our outpatient clinic using home-use electronic sphygmomanometers.

Effect of an angiotensin II type 1 receptor blocker, valsartan, on neurohumoral factors in patients with hypertension: comparison with a long-acting calcium channel antagonist, amlodipine.

This study compared the effects of amlodipine and valsartan on the sympathetic nervous system, the renin-angiotensin-aldosterone system, and brain natriuretic peptide, which are considered important parameters of the long-term prognosis. Seventy-three elderly patients, who had received antihypertensive treatment for more than 6 months with amlodipine, participated in this study. They were randomized to the V group (n = 36) and switched to valsartan from amlodipine, or to the A group (n = 37), which continued treatment with amlodipine.
