Abstract
IntroductionPhysiological cardiac hypertrophy and dilation are common findings in heavy physical load activity. We carried out this study to investigate the relationship between construction work and cardiac parameters adaptations, by comparing healthy masons to office workers on heart ultrasound.MethodsThe study was carried out on, 50 construction workers and 50 office workers matched for their weight, height and age. Systolic and Diastolic blood pressures, Left Ventricular diameter and thickness, Septum wall thickness and Left ventricular mass index were measured and calculatedResultsHeart rate, systolic and diastolic blood pressures were lower in construction workers, as compared to office workers: respectively 63±7 bpm vs. 75±6 bpm (p = 0.000); 120.1±7 mmHg vs. 130.5±9 mmHg (p = 0.000) and 68.5±7 mmHg vs. 77.0 ±9 mmHg (p = 0.000). Construction workers had a thicker septum and posterior wall: respectively 10.3 ± 1.1 mm vs. 8.9 ± 0.9 mm (p = 0.000); and 9.0 ± 1.2 mm vs. 8.1 ± 0.8 mm (p = 0.000).ConclusionConclusion We deducted that heavy load work has an impact on the heart mensuration. The past occupational history has to be taken into consideration during initial medical assessing of a worker in for a new job so as to avoid erroneous conclusions.

Physiological cardiac hypertrophy and dilation are common findings in heavy physical load activity
We carried out this study to find out if there was a physical and physiological cardiac alteration on echography observed in construction workers as compared to office workers that could be due or attributed to their occupation
The analysis indicated that there was a significant lower heart rate, Systolic and diastolic blood pressure in construction workers at rest as compared to office workers, but all remaining within the normal ranges, showing no pathological values
Summary
Physiological cardiac hypertrophy and dilation are common findings in heavy physical load activity. We carried out this study to investigate the relationship between construction work and cardiac parameters adaptations, by comparing healthy masons to off ice workers on heart ultrasound. Informal workers are not followed in regards to safety and health despite the fact that they are all exposed to hazards and environmental health risks They are more prone to health and safety hitches due to the fact that they are mainly less cultured and educated regarding the risks at work settings. We examined 50 health workers, all male waged in Douala municipality in Cameroon, occupied in construction informal activity, and compared them with 50 health office workers matched for gender and age. We carried out this study to find out if there was a physical and physiological cardiac alteration on echography observed in construction workers as compared to office workers that could be due or attributed to their occupation
