During April 1991-June 1993
PTMC (Inoue method) was per-
formed on 102 subjects with symp-
tomatic mitral stenosis, consist of
32 males and 70 females, Mean
of age was 33,12 ± 10.50 years.
Atrial fibrillation was found in 42,2%
of patients. All patients had mitral
valve score (Wilkins) 8 and 53,9%
patients had moderate-severe
pulmonary hypertension. Mitral
regurgitation (MR) +1 was found
in 15,6% patients and MR +2 in
4,1%. Immediate after PTMC, the
mitral valve gradient, pulmonary
artery pressure, left atrial pressure
and pulmonary vascular resist-
ance were decreased signifi-
cantly (p<0.05). Mitral valve area,
cardiac output, pulmonary func-
tion and functional capacily were
increased significantly (p < 0.05).
PTMC was successful in 92.1 5%,
suboptimal in 5,88% of patients.
The complications of the proce-
dure were cardiac tamponade
(1%), severe mitral regurgitation
(1%), death (3%) and artificial
ASD (11.8%).
We concluded that PTMC is a
relatively safe alternative proce-
dure with good immediate out-
come.

FACTORS INFLUENCING THE PHY
SICAL FITNESS AMONG HIGH-
SCHOOL STUDENTS IN JAKARTA

The purpose of this analysis
was to provide information on
the relationship between max
VO
2
and several variables includ-
ing sex, body mass index (BMI),
physical exercise, age, hemo-
globin (Hb) among Senior High
School students in Jakarta. A
linear regression model was
applied to demonstrate such re-
lationship using data collected
by the Physical Fitness Study on
Senior High School Students in
Jakarta.
A total of 1016 students (95%
were 12-19 years of age) consist-
ing of 54% boys and 46% girls were
involved in the study, and the
VO
2
max was measured through
the ciclo ergometry test; among
those tested, the cardiorespira-
tory endurance of 52% of
samples was considered as bad.
The VO
2
of boys was 7 ml/kg
body weight/minute greater than
of girls. The average VO
2
max of
boys was 38.01 ml/body weight/
minute, while the average of
girls was 30.82 ini/body weight/
minute. VO
2
max was signifi-
cantly influenced by sex, age,
BMI, physical exercise and Hb.
An increase of 1 kg/m
2
BMI was
followed by a reduction of 1.05
ml/kg body weight/minute VO
2
max. A monthly increase of physi-
cal exercise by 1 hour was follow-
ed by an increase of 0.02 ml/kg
body weight/minute VO
2
max. A
one year increase of age was
followed by a 0.47 ml/kg body
weight/minute reduction of VO
2
max. The reduction of VO
2
max
was occured earlier than of the
general cases. An increase of 1
g/100 ml Hb was followed by the
reduction of 0,31 ml/kg body
weight/minute VO
2
max. These
five variables explained the 25%
variations of VO
2
max.
