Diagnostic value of magnetocardiography in patients with coronary heart disease and in-stent restenosis.

Background: In-stent restenosis (ISR) has become one of the most challenging problems in patients with coronary heart disease. At present, using non-invasive methods to assess ISR is a hot topic. In this investigation we attempted to explore the potential of magnetocardiography (MCG) in diagnosis of in-stent restenosis.

[A survey of factors influencing prognosis and control rate for patients with hypertension in mainland China].

Objective: To observe the risk factor stratification and prevalence of target organ damage in hypertensive patients before therapy and blood pressure control rate after 4 or 12 weeks antihypertensive drug therapy.

Methods: In this prospective survey, data on cardiovascular risk factors, target organ damage and concomitant disease were collected in 26 655 hypertensive patients. Among them 26 325 and 3457 patients were recruited for antihypertensive drug therapy for 4 and 12 weeks, respectively and blood pressure control rate was determined.

[Effects of antidepressant therapy in patients with suspected "angina pectoris" and negative coronary angiogram complicating comorbid depression].

Objective: We observed the therapeutic effectiveness and safety of different antidepressants as well as the correlation between symptomatic improvement of depression and improvement of chest pain in patients with susceptible "angina pectoris" and negative coronary angiogram complicating comorbid depression.

Methods: In this double-blinded randomized study, a total of 123 eligible patients were allocated into three groups: (1) Group F: fluoxetine 20 mg QN (n = 41); (2) Group P: Placebo 1 tablet QN (n = 40); (3) Group F + O: fluoxetine 20 mg + olanzapine 2.5 mg QN for the former 2 weeks and only fluoxetine 20 mg QN for the latter 2 weeks (n = 42).
