Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Coronary heart disease has remained the leading cause of death worldwide over the past decades. Unstable angina is a clinical syndrome intermediate in severity between stable angina and acute myocardial infarction with high morbidity and mortality. Standard drug therapy and invasive revascularization are effective in decreasing progression to infarction, reducing symptoms and multiple hospitalizations, in most cases without a decrease in the long-term mortality rate. However, there are still many patients with persistence or recurrence of angina despite standard medical therapy and/or revascularization. Wen Xin granule, as a Chinese herbal medicine has shown great effect in patients with unstable angina in our clinical. However, there is still insufficient evidence on his specific efficacy and safety. Therefor, we'd like to evaluate the efficacy and safety of Wen Xin granule in patients with unstable angina through this multi-center, double-blind, randomized placebo-controlled trial.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Major adverse cardiovascular events
Time Frame: Record the incidence of major adverse cardiovascular events in one year by follow-up.
Including recurrent angina, acute myocardial infarction, severe arrhythmia, heart failure, and cardiac death.
Record the incidence of major adverse cardiovascular events in one year by follow-up.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
The thrombelastograph
Time Frame: Before treatment and at eight weeks after treatment.
Parameters assessed by were R (represent clotting time), K and Angle (reflect clot strength and development), MA (maximum platelet-fibrin clot strength), CI (represents overall coagulability), and LY30 (represents lysis).
Before treatment and at eight weeks after treatment.
TCM symptom scale score
Time Frame: Before treatment, four and eight weeks after treatment.
TCM syndrome scale includes items of chest tightness, chest pain, heavy body, obesity, phlegm, dark complexion, tongue condition and pulse condition. The chest tightness and chest pain, have 4-grade options of none, mild, moderate and severe, marked as 0, 2, 4 and 6 respectively. The other items have two options of yes or no, marked as 0 and 1 respectively. The higher scores mean more serious symptoms.
Before treatment, four and eight weeks after treatment.
Seattle angina questionnaire
Time Frame: Before treatment, four and eight weeks after treatment.
The SAQ regroups 19 items measuring five specific scales: physical limitations, anginal stability, anginal frequency, treatment satisfaction and disease perception targeting a specific disease and treatment group. Higher scores mean a better outcome.
Before treatment, four and eight weeks after treatment.
