“…Previous studies reported that in smokers the increased sympathetic activity and decreases in the parasympathetic activity further causing diminished myocardial oxygen supply. 10 This increased stimulation to the sympathetic nervous system may contribute towards the increased heart rate as well as blood pressure in smokers. Previously Sharma et al have shown that abnormalities in ECG parameters were significantly more prevalent in smokers as compared to non-smokers (56.66 % Vs 6.00 %) (p <.0001).…”

The nicotine present in the cigarette smoke induces conduction block, acts as a cardiac A-type potassium channels blockers and increase the ventricular fibril formation which also changes the cardiac electric impulses usually assessed via electrocardiogram (ECG). The present study aims to evaluate and compare the ECG profile change in seemingly fit smokers and non-smokers.The present study was conducted in the Department of Medicine, for two years involved 148 patients evaluated for different parameters heart rate, the PR interval, QRS complex QTc (corrected QT interval) using a 12 lead ECG. P-value < 0.05 denotes statistical significance. All the patients were male and the mean age was comparable in non-smoking group (NS) vs smoking group (S) (29.26±5.90 vs. 30.42±6.19 years; p=0.244). Mean systolic (127.43 ± 7.29 (S) vs. 123.03 ± 6.96 (NS) mm Hg; p<0.001) and diastolic BP (80.08 ± 5.15 (S) vs. 77.32 ± 5.76 (NS) mm Hg; p=0.003) were significantly high in smokers. Prolonged QTc interval was noted in 47.30% of the individuals of group S (p<0.001). The mean pulse, QTi, and QTc were significantly high in group S (p<0.001) while the mean respiratory rate (RR) interval was significantly low (p<0.001). There was an increasing trend in terms of pulse, QTi, and QTc based upon increased smoking index while PR interval was significantly high in mild smokers compared to moderate and heavy smokers (p<0.001).Smokers show abnormalities in the ECG profile that may eventually increase the risk of incidence of cardiovascular diseases.

Hypertension is a public health problem. Failure to control blood pressure figures is responsible for morbidity and premature mortality. This study aims to describe the characteristics of hypertensive patients followed at primary health care centers in Marrakech. Between May 2021 and December 2022, a cross-sectional study of 922 hypertension patients attending primary health care centers in Marrakech was done. To gather socio-demographic, behavioral, and clinical data, as well as hypertension treatment features and the care-patient-physician triad, a face-to-face questionnaire was employed. To identify risk factors associated with uncontrolled blood pressure, multivariate logistic regression was used. Uncontrolled blood pressure was found in 73.5% of people. The patients' average age was 63.4 ± 9.4 years (mean ± standard deviation), and 524 (77.3%) were women. Tobacco consumption (Adjusted Odd Ratio of 4.34; 95% CI [1.58–11.9]); lack of self-monitoring of hypertension (AOR of 1.69; 95% CI [1.14–2.52]); a family history of hypertension (AOR of 1.58; 95% CI [1.12–2.22]); overweight or obesity (AOR of 1.73; 95% CI [1.15–2.58]); and nonadherence to antihypertensive medication (AOR of 1.58; 95% CI [1.05–2.38]) were identified as risk factors for uncontrolled blood pressure. In hypertensive individuals, the percentage of uncontrolled blood pressure is considerable. It is essential to provide therapeutic education classes for hypertension patients in order to strengthen their power and autonomy in managing their hypertension.
