All patients admitted at Jose R. Reyes Memorial Medical Center, Philippine Heart Center and Veterans Memorial Medical Center from September 1998 to February 2001 who presented with inferior wall MI were entered in the study. Patients with onset of symptoms within 48 hours of evidence of chest pain, elevated CPK, and ST segment elevation in >2 inferior leads were included. The demographic profile, killips class on admission were recorded. Highest ST ECG were classified into pattern 1 (J/R ratio <50%), pattern 2 (J/R ration >_ 50% in >_ 2 inferior leads), pattern 3 (presence of early Q waves) and the presence or absence of ST depression (>2 small squares, >0.08 second duration in >2 contiguous pre-cordial leads). The occurrence of HGAVB, hospital mortality, duration of hospital stay were part of the evaluation.
Cross sectional design and cohort study.
JRRMMC, PHC & VMMC, September 1998 to February 2001
94 patients with acute inferior wall MI during the specified time period.
Therefore, the J-point/R-wave >0.5 in >2 leads and JR ratio average >50% are predictors of the development of HGAVB among patients with inferior wall MI. Patients with HGAVB have longer hospital stay and have higher incidence of worsening killip class.
1. To determine if the following variables are seen in patients who develop HGAVB:
d. Diabetes mellitus
e. Smoking history
f. Killips class on admission
g. J/R average
2. To determine the incidence of HGAVB in ECG pattern 1, 2, 3 and ST depression.
3. To determine the differences in clinical outcome in patients with or without HGAVB
a. Duration of hospital stay
b. Cardiac mortality
c. Worst killips
