Diagnosis made by physician. Patient on chronic pharmacologic therapy and/or have a FEVI less than 75 percent of predicted value.

Indicate if the patient has cerebrovascular disease, documented by any one of the following:

1. Cerebrovascular Accident (CVA): Patient has a history of stroke, i.e., loss of neurological function caused by an ischemic event with residual symptoms at least 24 hours after onset.
2. Reversible Ischemic Neurologic Deficit (RIND): Patient has a history of loss of neurological function caused by ischemia with symptoms at least 24 hours after onset but with complete return of function within 72 hours.
3. Transient Ischemic Attack (TIA): Patient has a history of loss of neurological function caused by ischemia that was abrupt in onset but with complete return of function within 24 hours.
4. Unresponsive Coma greater than 24 hours: Patient experienced complete mental unresponsiveness and no evidence of psychological or physiologically appropriate responses to stimulation.
5. Non-invasive/invasive Carotid Test with greater than 75% occlusion.
6. Previous Carotid artery surgery. (CEA)

Prior to PCI or history of either paroxysmal atrial fibrillation or chronic atrial fibrillation.

Any history of either out of hospital or in-hospital cardiac arrest. Cardiac arrest as evidenced by potentially lethal arrhythmia requiring cardioversion, defibrillation or CPR.

Indicate if the patient has had at least one documented previous ST or non-ST MI eight or more days prior to this admission.

Indicate whether the patient has had a previous Percutaneous Coronary Intervention (PCI) of any type (balloon angioplasty, atherectomy, stent, thrombectomy or other), performed prior to the current admission.

This intervention is part of a staged procedure. Intervention (PCI) to intervention (PCI), not diagnostic cath only.

The patient is undergoing CPR en route to the lab and/or prior to the intervention, including hemodynamically unstable patients.

Was a cardiac arrest the primary indication for the current coronary intervention?

PCI performed in same setting as coronary angiography.

Angina without a change in frequency or pattern for the six weeks prior to this procedure. Angina is controlled by rest and/or oral or transcutaneous meds.

Pain, pressure or discomfort in the chest, neck or arms not clearly exertional or not otherwise consistent with pain or discomfort of myocardial ischemic origin. (Includes patients presenting with CHF symptoms only presumed to be ischemia).

The patient was hospitalized for unstable angina documented in the medical record with serial ECGs and biochemical profiles. One of the following criteria are necessary:

1. Angina at rest (usually prolonged >20 mins),
2. New onset (less than two months) exertional angina of at least Canadian Cardiovascular Society Classification (CCSC) class III
3. Recent (less than two months) acceleration of angina reflected by an increase in severity of at least one CCSC class to at least CCSC class III. The patient must also NOT have any biochemical evidence of myocardial necrosis.

Is the primary indication for coronary intervention a preoperative evaluation and subsequent intervention prior to major noncardiac surgery: e.g. major abdominal surgery, vascular surgery including fem-pop bypass, AAA repair, aortic root repair, ORIF, or knee replacements etc.

Was patient evaluated by thoracic surgery and felt not to be a surgical candidate (for whatever reason i.e. no conduits, severe COPD, small distal vessels, etc.) Must be refused by CV surgeon.

Cardiogenic shock is defined as a sustained (>30 minutes) episode of systolic blood pressure < 90mmHg, and/or cardiac index <2.2 L/min/m2 determined to be secondary to cardiac dysfunction, and/or the requirement for parenteral inotropic or vasopressor agents or mechanical support (e.g., IABP, extracorporeal circulation, ventricular assist devices) to maintain blood pressure and cardiac index above those specified levels. (Def #8005 in NCDR 4.3.1)

Recurrent ventricular tachycardia or ventricular fibrillation prior to PCI (occurred greater than one time).

Has the patient had a Myocardial Infarction (ST elevation or non-ST elevation) within the previous 7 days?

PCI performed as the primary intervention on the infarct artery i.e. no thrombolytics were administered and PCI was performed within 12 hours of symptom onset.

Mark this box if the time from symptom onset to balloon dilatation was 0 to 6 hours.

Between 6 to 12 hours elapsed from symptom onset to balloon dilatation.

Between 12 to 24 hours elapsed from symptom onset to balloon dilatation.

Greater than 24 hours elapsed from symptom onset to balloon inflation.

Percutaneous coronary intervention performed on the infarct related artery.

Continued symptoms of angina after thrombolytic therapy.

Indicate whether patient received lytic therapy as primary treatment of AMI. Include any combination ½ dose lytics given. (eg, TNK, TPA, and RPA).

Is/Was the patient on intravenous heparin prior to the procedure?

Indicate as a percentage from 0-100 as obtained from a LV gram, MUGA, ECHO, or estimated from other calculations, based upon available clinical data. If the LVEF is documented as normal without a numerical value, enter 55%. Record the EF obtained closest to PCI.

Visual estimate of saphenous vein graft, left internal mammary artery, right internal mammary artery, including any anastamotic lesions with ≥70% stenoses.

Includes LAD, RCA, LCX, and Ramus. This does not include branches off the native vessels. For example, if a patient has a ≥ 70% lesion in the OM, proximal LCX, and the mid LAD, mark it as two.

Left ventricular end diastolic pressure.

Mark the box if the index vessel is a saphenous vein, LIMA, or RIMA graft.

From the origin up to 3 mm.
