The objective of the Heart Catherization Registry was to quantify the waiting times, morbidity and mortality of patients waiting for catheterization, and to identify predictors of cardiac events that occur while patients are waiting.

The study reported that patients awaiting cardiac catheterization, may experience major adverse events, such as death, myocardial infarction and congestive heart failure, which may be preventable.

These findings impacted health care delivery in Canada contributing to increased heart catheterization facilities and improved prioritization schemes that allow earlier access for patients at higher risk.

Primary Outcome:

Cancellation of the procedure, death, MI, congestive heart failure (CHF) and other hospital admission for a primary cardiac diagnosis. Events were not adjudicated.
