Trial summary

Mental stress-induced myocardial ischemia(MSIMI) has been recognized a significant clinical problem. Evidence has shown that individuals with MSIMI have 2 to 2.5 times higher risk to develop a major averse cardiovascular events over 3-5 years, compared to their counterparts who have no MSIMI.

About this study

Official title: Effect of Mental Stress on Myocardial Perfusion and Myocardial Blood Flow in Women With Chest Pain and Coronary Artery Stenosis Less Than 50%

Mental stress-induced myocardial ischemia(MSIMI) has been recognized a significant clinical problem. Evidence has shown that individuals with MSIMI have 2 to 2.5 times higher risk to develop a major averse cardiovascular events over 3-5 years, compared to their counterparts who have no MSIMI. Nevertheless, investigations into the study of MSIMI among women who have chest pain but artery stenosis < 50% have been lacking. In this project, the investigators used positron emission tomography (PET) to evaluate perfusion defect during mental stress to diagnose MSIMI. Women with chest pain and coronary artery stenosis < 50% were included as the experimental group, age-matched healthy people as the control group, the aim of this study is to compare the incidence of MSIMI in the two groups. At the same time, the study also observe the change of MBF during mental stress and the relationship between MBF and MSIMI.

Read the detailed description

The goals of this project are to assess MSIMI prevalence in chest pain women with coronary artery stenosis less than 50%, as compared to age matched healthy women, and the MBF change during mental stress and adenosine vasodilator stress by PET with N-13 ammonia . This study will also establish the methodology of echocardiography to diagnose MSIMI by comparing with PET. To evaluate the consistency of myocardial blood flow (MBF by PET-CT) and peripheral blood flow (PAT ratio by EndoPAT) during stress test. and to explore the pathogenesis of MSIMI from aspects of neuroendocrine mechanism, sex hormone level, humoral immunity index and proteome expression.

The stress testing will be conducted at the PET-CT and echocardiography unit of Guangdong Provincial People's Hospital. Following a 20-minute calibration-rest period, participants will be asked to complete a series of 3 consecutive mental stress tasks. The mental stress tests are embedded in the virtual reality device, and the subjects can carry out the mental stress test with the virtual reality device on their heads. (1) Stroop Color-Word test, is administered by computer on a video monitor. A word appeared in the middle of the screen-Red, Green, Yellow, or Blue-in one of these four colors. At the bottom of the screen the words Red, Green, Yellow, and Blue appeared with the font color not matching the word meaning. The participant is asked to match the color of the word in the middle of the screen with the meaning of the color word at the bottom by clicking on the correct option, which lasts about 4 minutes. and then (2) Public speaking with anger recall: during this test, patients will be asked to give a speech on a recent situation in which they experienced anger to an audience of three observers (doctors) after 1 minute of preparation. Prior to the speech, subjects are told that their speech will be evaluated on their description of the situation, as to what happened, what they thought, felt, what they did, and what happened as a result. If they run out of things to say, the research tech will prompt them with questions to elicit more content until the three minutes are up. and at last the (3) Mental arithmetic: during this test, patients will be asked to perform a series of serial subtractions beginning at a given number which will be different for each repeated test and will be chosen by the tester from a fixed list of various numbers, with encouragement to perform calculations as quickly as possible; Each mental stress lasts for 4 minutes, there is no rest between the two mental stress, and the whole process of mental stress is 12 minutes.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Mental Stress TestDiagnostic test

    In this study, we compare MSIMI prevalence in the two groups (chest pain group and no chest pain group). Each subject in both groups receive the same mental stress test process, and the mental stress test process have 3 consecutive stress tests, which including: Stroop Color-Word test; Public speaking with anger recall test and Mental arithmetic test.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. MSIMI (Measures as perfusion deficit with mental stress test via PET-CT) prevalence in chest pain women with coronary artery stenosis less than 50%, as compared to age matched healthy women.

    Percentage of participants wih an presence of mental stress-induced myocardial ischemia (MSIMI) during the 3 mental stressors.

    MSIMI is defined by the following: compared to rest, 1) Each myocardial segment was scored from 0 to 4, with 0 being normal, 1 possibly normal, 2 definitely abnormal, 3 severely abnormal, and 4 no perfusion. The investigators calculated summed scores in a conventional fashion, including a summed stress score, a summed rest score, and a summed difference score. A summed difference score ≥3 is typically used as evidence of MSIMI.

    Measured: half an hour

  2. The MBF change during mental stress test

Secondary outcomes (7)
  1. Blood flow reserve in women with chest pain and coronary artery stenosis < 50% .

    Bood flow reserve of participants using Adenosine

    Measured: half an hour

  2. The consistency of PET-CT myocardial scanning and color Doppler echocardiography (contrast echocardiography, spot tracking) for the diagnosis of MSIMI.

    The consistency between PET-CT and Doppler echocardiography (contrast echocardiography, spot tracking) in diagnosing MSIMI

    Measured: 30 days

  3. The consistency of myocardial blood flow (MBF by PET-CT) and peripheral blood flow (PAT ratio by EndoPAT) under pressure test.

    The consistency between myocardial blood flow and peripheral blood flow during mental stress test

    Measured: 2 hours

  4. The neuroendocrine change in MSIMI(+) group, as compared with MSIMI(-) group.

    The cause of MSIMI

    Measured: 1 hour

  5. The difference of sex hormone level between MSIMI(+) group and MSIMI(-) group

    Measured: 1 hour

  6. The difference of humoral immunity index level between MSIMI(+) group and MSIMI(-) group.

  7. The difference of proteome expression level between MSIMI(+) group and MSIMI(-) group.

    The cause of MSIMI

    Measured: 2 days
