The abstract of the article states the results: 'Compared with never exposed participants, subjects chronically exposed to occupational noise had a 2-3-fold increased prevalence of angina pectoris, myocardial infarction, CHD and isolated diastolic hypertension.'
Thus, noisy work environments increase the risk of coronary heart disease (CHD) and hypertension by two to three times.
And, 'After adjustment for various covariates, the odds ratios (95% CIs) for angina pectoris, CHD and isolated diastolic hypertension were 2.91 (1.35 to 6.26), 2.04 (1.16 to 3.58) and 2.23 (1.21 to 4.12), respectively.'
The risk for angina pectoris increased 2.91 times when working in a noisy work environment, while the risk for coronary heart disease was raised 2.04 times and for diastolic hypertension was increased by 2.23 times, each while working in noisy work situations.
Angina pectoris, commonly called angina, causes severe chest pain due to a lack of blood to the heart muscle.
Coronary heart disease (CHD) is a problem with blood circulating through the heart (cardiac muscle) and surrounding tissue.
Diastolic hypertension (HTN), or high blood pressure, is caused by an abnormally high systemic arterial blood pressure. Diastolic blood pressure is the pressure between heartbeats (resting heart); the second number (lower number) in a blood pressure reading.
