Filter by:A multicentre, post-marketing, observational trial in 450 patients, whose standard diagnostic workup for chronic coronary syndromes provided for Invasive Coronary Angiography (ICA). Medical records of a potential subject of the trial before their enrolment contain a good quality result of at least 128-slice CCTA performed up to 3 months before the elective ICA. CCTA should find at least one ≥50% stenosis in at least one big coronary artery of ≥ 2 mm diameter. At one hour before ICA in the latest the patient should have a resting Continuous Non-Invasive Blood Pressure (CNBP) taken with a certified device delivered by LifeFlow. The last criterion before including a patient in the final analysis is at least one significant (≥50%) stenosis in one or two coronary arteries of ≥ 2 mm diameter visually confirmed by ICA with a FFR measurement taken in these arteries. The data collection period will cover time from admission for the elective ICA to discharge from the hospital (evaluation of possible adverse events related to invasive procedures). After initial qualification of available data by the attending physician, selected patients will be asked for a consent to participation in the trial no later than upon admission for the elective ICA and before CNBP measurement.
The aim of this prospective cohort study is to assess the quality of therapy in patients with stable ischemic heart disease (IHD) who had never applied for specialized medical care for the last 3 years and try to accord their treatment with current clinical guidelines.
Exercise treadmill test (ETT) is frequently done, inexpensive, relatively safe investigation for diagnosis of ischemic heart disease and prediction of exercise capacity. Ischemic heart disease is increasing by leaps and bounds all over the world even in the developing countries like Bangladesh. The incidence rate of coronary artery disease (CAD) is not limited to male gender as previously seen. As a cause of industrialization and increased life expectancy, incidence of ischemic heart disease in females is escalating now in Bangladesh also. Though ETT is a well accepted investigation to diagnose CAD, it has a high false positive and false negative result if ST segment response alone is calculated for interpretation of the test. Duke Treadmill Test and Simple Treadmill Test are valid and well known scores which can predict coronary artery disease burden more efficiently than ST segment response alone. Computer generated Cleveland clinic score is another valid treadmill score which has a complex algorithm but effective way to predict 3 year and 5 year survivability. These three scores are well tested on western population but to our best knowledge there is little or no information regarding their predictability of CAD in Bangladesh. It's well known that ETT has a high false positive result in female population, so applying the scores may render ETT more efficient and abrogate unwanted risk of undergoing coronary angiography to diagnose CAD in females. In this study the investigator will try to find out the accuracy of commonly applied treadmill scores and ST segment response to diagnose CAD as well as accuracy of computer generated Cleveland Clinic Score will be tested. Total 110 people including male and female will be included according to inclusion and exclusion criteria and informed written consent will be taken. The patients who have undergone ETT and coronary angiogram with in six months for confirmation and identification of coronary artery disease in accordance with the recommendation of ACC guideline for CAG will be selected . All available data will be analyzed using SPSS. The accuracy of different scores will be calculated and compared with each other. According to currently available data from studies in western population the treadmill scores will have good predictability and will be efficient to abolish high false positive result in female population in Bangladesh.
