Interventional procedures versus medical therapy alone: outcome of cardiac patient management. A systematic review.

BACKGROUND
Cardiac patients are managed medically or with an intervention. This review aims to explore the survival benefit of each approach in the management of cardiac patients.


METHODS
We reviewed updated evidence of survival benefit from the most recent trials and guidelines.


RESULTS
Patients with ST-segment-elevation myocardial infarction (STEMI) have a mortality benefit when a Primary Cardiac Intervention is implemented. No similar benefit has been shown in chronic stable coronary artery disease. Heart failure patients show a mortality benefit using medication and similarly, mild or moderate valve disease patients do not require an intervention. In atrial fibrillation, the CABANA trial using ablation therapy, had no mortality benefit. Hypertension drug therapy showed a significant mortality benefit, a similar benefit was noted with drug therapy for the treatment of dyslipidemia, when achieving the target lipid goal.


CONCLUSIONS
Not all interventional procedures result in a mortality benefit. Medical therapy alone increases survival in many cardiac diseases.
