Conditions

Health Condition 1: I209- Angina pectoris, unspecified

Interventions

Intervention1: New low dose angiography: A comparative arm where the patients being once eligible for the study
would undergo angiography using the new low dose protocol. A total of 5 to 8 different (orthogonal) views would be taken (2 for RCA and 4 to 6 for LAD/LCX) Control Intervention1: Standard dose angiogr

Eligibility

Inclusion criteria

Inclusion criteria: Adult patients who qualify for a need of diagnostic angiography and are finally found to have normal epicardial coronaries, e.g.: 1. Pre aortic or mitral valve replacement angiography 2. TMT positive for inducible ischemia 3. SPECT MPI positive patients 4. Cradiologically symptomatic patients with ECG abnormalities, who cannot be subjected to stress test (DCMP, LBBB, LVH) 5. High risk pre transplant patients

Exclusion criteria

Exclusion criteria: 1. Those who are unwilling for study 2. Patients who come with acute coronary syndrome like STEMI or NSTEMI

Design outcomes

Primary

MeasureTime frame
To determine the difference in the radiation exposure levels received by patients undergoing diagnostic angiography with and without the new low dose exposure protocol.Timepoint: At baseline and at the end of full enrolment which is likely to be 06 months (this is not a prospective study, and there is no follow up. the data is collected at baseline and further analysed when the sample size in completed)—

Secondary

MeasureTime frame
1. To evaluate the diagnostic image quality obtained with the new low dose exposure protocol compared to the standard protocol. 2. To assess any potential limitations associated with the new low dose exposure protocol. Timepoint: Outcome will be assessed at baseline & after completion of the sample size which is likely to occur by 06 months. This is not a prospective study, & there is no follow up. the data is collected at baseline & further analysed when the sample size in completed—
