STREAM-2: Half-Dose Tenecteplase or Primary Percutaneous Coronary Intervention in Older Patients With ST-Segment-Elevation Myocardial Infarction: A Randomized, Open-Label Trial. Based on this, the authors did a literature review and found that there is an increasing rate of ICH and major non-intracranial bleeding starting at ≈60 years of age.

The arterial pressure waveform is transduced using the coronary catheter. Normally, the diameter of the coronary artery ostium is much greater than the diameter of the catheter so that catheter engagement does not significantly impair antegrade coronary perfusion. Here is the ECG and arterial waveform during RCA angiography.
