Key result
Patients with significant coronary disease had similar systolic pulmonary artery pressure to those with patent vessels (31 vs 26 mmHg, NS), suggesting routine right-heart cath adds little value.
Why the study?
Does routine right-heart catheterization provide additional prognostic information in patients undergoing coronary arteriography for coronary artery disease?
Observational (n=100)

Absolute Event Rate: 31% vs 26%
p-value: p=NS
Routine right-heart catheterization in patients with coronary artery disease does not provide additional information for determining prognosis or suitability for coronary bypass surgery.

Routine right-heart catheterization may yield incremental hemodynamic data during coronary angiography; leaves open its routine use in all patients.
Howard S. Frıedman (1978) conducted an observational in Coronary artery disease (n=100). Significant coronary disease (>70% stenosis) vs. Patent coronary vessels was evaluated on Systolic pulmonary artery (PA) pressure (mmHg) (p=NS). Patients with significant coronary disease had similar systolic pulmonary artery pressure to those with patent vessels (31 vs 26 mmHg, NS), suggesting routine right-heart cath adds little value.
