“…Indeed, a raised heart rate and blood pressure have been demonstrated immediately after the siesta, in a very similar fashion that happens after waking up in the morning [16], leading to an increase in cardiovascular events. A recent study from a wide Spanish population demonstrates the relationship between cardiovascular risk factors (mainly smoking habit) and circadian onset of MI [17]. Unfortunately, one limitation of the present study is that we have not examined detailed pathophysiological mechanisms (e.g.…”

“…For instance, alteration of circadian rhythms due to altered sleeping pattern can cause derangements in several psychophysical and metabolic functioning of the body [57] and CVD risk factors including aging, diet-induced obesity, T2DM, hypertension and dyslipidemia and therefore augments the development of CVD. Lopez et al & Merikanto et al [58,59] reported association between sleep disorders and raised BP, smoking and re-infarction.…”

Background/Aim: There is a global increase in life-style related risk factors for CVD. However, few studies have examined the prevalence of these factors in the general population at different social settings/gathering such as night clubs, drinking points/bars and discotheques where different lifestyle habits are freely displayed. Identifying such factors can lead to innovative strategies for improving cardiovascular health. The aim of this study was to determine the prevalence of lifestyle, clinical and biochemical risk factors for CVD among night clubbers in Southern Nigeria.Methods: Anthropometrics, questionnaires, clinical and blood samples were collected from 255 participants who were classified as night clubbers (n=130) and non-night clubbers (n=125) and analyzed for body mass index (BMI), waist circumference (WC), socio-demographics, life style related behaviors, blood pressure indices, lipid profile and markers of insulin resistance using standard methods. Results: Compared to non-clubbers, night clubbers had significant higher prevalence of CVD risk factors including habitual alcohol consumption (P<0.001), physical inactivity (P=0.026), poor dietary habits (P<0.001), short sleep duration (P<0.001), abnormal lipid sub fractions (high serum TG, T-chol and LDL levels) (P<0.001), raised blood pressure indices (SBP, DBP, MAP) (P<0.0001), raised serum uric acid level (P<0.0001) and a marker of insulin resistance (HOMA-IR) (P=0.060). Conclusion: CVD risk factors are more prevalent among night clubbers than non-clubbers. Night club, discotheque, tavern, drinking point and bar patrons should be included among target populations in development of interventions necessary to reduce the high prevalence of CVD risk factors in the general population, because current risk factors become future diseases and public health burden. Knowledge of risk factors can be used to shift their population distribution.

“…20,21 The morning peak in the subgroup of hypertensive patients in the present study, is explained by the increased sympathetic stimulation and haemodynamic changes caused by catecholamines, and agrees with findings of other studies as well. 22 In addition, rapid eye movement (REM) sleep is characterised by explosions of the sympathetic tone, resulting in an increase of BP and heart rate over the second half of the night. 23 Increased BP during the night is related with high CV risk.…”

“…Almost half of the patients were smokers. 31 This might be explained by the fact that smoking is found to activate the sympathetic nervous system 22 and enhance platelet aggregation and thrombogenicity. 32,33 Unfortunately, the smoking rate in Cyprus is high (31%) 34 and it is obvious in the current study even though the whole sample is quite small.…”

Introduction: The circadian rhythm of onset of myocardial infarction shows an increased risk during the morning hours. However, it is not clear whether habits, culture and sunshine hours differentiate circadian rhythm. The aim of this study was to investigate the influence of cultural factors on the circadian rhythm of acute myocardial infarction with ST segment elevation in a Mediterranean island. Method: The study was a retrospective correlational survey. It included 123 patients with ST elevation myocardial infarction (mean age 60.7±12.6; 82% men). The 24 h of a day were divided into four six-hour periods of time for study purposes (00:01–06:00; 06:01–12:00; 12:01–18:00; and 18:01–24:00) and the chi-square test was used for the analysis. Results: A morning peak of symptoms onset of ST-elevation myocardial infarction was detected during the period 06:01–12:00 ( p=0.044). In patients who were smokers, a bimodal pattern involving a morning (06:01 –12:00) and an afternoon-to-night peak (18:01–24:00) ( p=0.005) was detected. For patients with a history of hypertension, a morning peak of their symptoms was also detected ( p=0.028). Different circadian variations were found between patients over the age of 60 years old and patients under the age of 60 years old ( p=0.025). Conclusions: Patients with ST elevation myocardial infarction seem to follow a circadian rhythm with a peak of onset of symptoms in the morning. In the smokers’ subgroup, a different circadian pattern was found. The habit of smoking is likely to affect the circadian rhythm of the onset of ST elevation myocardial infarction in the Mediterranean area and culture.
