OBJECTIVE: The present study was designed to observe the influence of smoking and hypertension on left ventricular mass (LVM), both individual and the combined effect. METHODS: This study was conducted in the Department of Medicine, SMS Medical College Hospital, Jaipur. Hundred patients were included in the study. They were divided into four groups--non smoker normotensives, non-smoker hypertensives, smoker normotensives and smoker hypertensives. They were also divided into smokers and nonsmokers and hypertensives and normotensive. Patients of age group 31-65 years of both sexes were chosen. Patients with secondary hypertension, diabetes mellitus, dyslipidemia, cardiomyopathies, valvular heart disease women on oral contraceptives were excluded from the study on the basis of history and relevant laboratory tests. An M-mode echocardiography was done and the LV mass was calculated by the formula proposed by Devereux et al. LV mass = 0.8 [1.04 (IVSd + LVIDd + LVPWd)3 - (LVIDd)3] + 0.6 gms RESULTS: The mean LV mass (in gms) in the four groups of nonsmoker normotensives, nonsmoker hypertensives, smoker normotensives and smoker hypertensives are 106.77 +/- 25.78, 165.3 +/- 42.55, 154.53 +/- 24.6 and 228.78 +/- 56.88 respectively. The comparison of mean LV mass (in gms) of smokers and nonsmokers were 191.66 +/- 40.74 and 136.04 +/- 36.16 (P < 0.001) respectively. The comparison of the mean LV mass (in gms) of hypertensives and nonhypertensives were 197.25 +/- 49.72 and 126.29 +/- 25.19 (P < 0.001) respectively. Comparison of the mean LV mass (in gms) of patient with two risk factors i.e., smokers hypertensives with patients without any risk factor i.e., nonsmoker normotensive were 228.78 +/- 56.88 and 106.77 +/- 25.78 (P < 0.001) respectively. While comparison of the mean LV mass (in gms) of patients with one risk factor each i.e., smoker normotensives and nonsmoker hypertensives were 165.3 +/- 42.55 and 154.53 +/- 24.6 (P < 0.05) respectively. CONCLUSION: Both smoking and hypertension cause an increase in LV mass, hypertension causing a more increase, than smoking, individually. Both smoking and hypertension combine together to increase the LV mass, more than either of them individually. Smoking by itself can cause an increase in LV mass independent of hypertension.

Increased left ventricular mass is an important risk factor in hypertension for various cardiovascular complications. We studied 49 patients of essential hypertension and the relationship between QT dispersion (defined as the difference between the maximum and the minimum QT interval in a 12-lead electrocardiogram) and M-mode echocardiographic left ventricular mass was analysed. Criterion of left ventricular hypertrophy was left ventricular mass index above 134 gm/m2 in men and above 110 gm/m2 in women. There were a total of 22 patients with left ventricular hypertrophy (15 men and 7 women). The mean QT dispersion was 82.66 +/- 35.34 milliseconds (ms) in men with left ventricular hypertrophy and 36.66 +/- 15.71 ms in men without left ventricular hypertrophy. The mean QT dispersion was 77.14 +/- 29.27 ms in women with left ventricular hypertrophy and 26.66 +/- 9.99 ms in women without left ventricular hypertrophy. The correlation co-efficient was 0.59 (p < 0.001) and 0.69 (p < 0.01) in men and women, respectively. Hence, we conclude that there is a direct, linear and positive correlation between left ventricular mass and QT dispersion in essential hypertension.

Drug Sensitivity of Salmonella typhi isolated from 30 blood culture positive cases of typhoid fever who presented between Nov. '93 to Aug. '94 was tested to determine their in vitro susceptibility to various antimicrobiols. 56.6% showed resistance to chloramphenicol, 70% to amoxycillin, 50% to amikacin, 43.3% to gentamycin, 40% to ampicillin, 33.3% to cotrimoxazole, 30% to cephalexin and very low resistance (6.6% each) to ceftriaxone and cefotaxime. All the 30 cases were sensitive to ciprofloxacin and ofloxacin. 17 chloramphenicol resistant typhoid cases in whom chloramphenicol was initially started failed to respond to this drug even after 4-5 days therapy, indicating that in vivo response matched with the in vitro sensitivity. Clinical response to ciprofloxacin, whether given initially or following chloramphenicol failure was prompt and satisfactory. Ciprofloxacin thus appears to be a good choice in such cases.
