Prognostic value of nitrate enhanced Tc99m MIBI SPECT study in detecting viable myocardium in patients with coronary artery disease.
Article in The international journal of cardiovascular imaging, 2003. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundAssessing the viability in akinetic myocardium is vital for predicting functional recovery after therapeutic management in patients with chronic coronary artery disease (CAD) and depressed left ventricular (LV) function. The present study aimed to evaluate the efficacy of Tc99m MIBI SPECT enhanced with nitroglycerine infusion in detecting myocardial viability, as well as to asses the relationship between the myocardial viability and the subsequent treatment and outcome of patients. METHODS AND
resultsSixty-seven consecutive patients with CAD and LV dysfunction (LV ejection fraction 36.6 +/- 8.4%) underwent Tc99m MIBI imaging--at rest and during intravenous nitroglycerine infusion--for viability assessment. Fourteen patients were treated pharmacologically (Group I), and fifty-three (Group II) were submitted to coronary revascularization (PTCR or CABG). Fifteen major cardiac events were observed during 25 months of the follow-up. A significantly worse event-free survival was registered in the subjects of Group I than in Group II subjects. The prognostic predictors of cardiac events were: (1) the number of viable, non-revascularized segments in perfusion imaging (p < 0.001), (2) the severity of the disease assessed by coronary angiography (p < 0.05).
conclusionsViability detection in nitroglycerine infusion enhanced Tc99m MIBI imaging offers significant prognostic value in patients with CAD after myocardial infarction. Patients with preserved viability showed better prognosis after revascularization than those treated pharmacologically.
