Risk factors and inflammatory markers in acute coronary syndrome-ST elevation myocardial infarction (STEMI).

OBJECTIVES: The increasing prevalence of coronary artery disease [CAD] poses worrying statistics. Atherosclerosis of coronary vessels is the main culprit for the spectrum of CAD especially acute coronary syndrome. Atherosclerosis is regarded as a consequence of inflammatory changes in the coronaries. Our study aimed to assess the role of risk factors and inflammatory markers with acute ST-elevation myocardial infarction [STEMI]. METHODS: 100 patients with ST-elevation Myocardial infarction [STEMI] and 100 age and sex matched controls were included in the study. A history of risk factors like smoking, hypertension, diabetes and hypertension was noted. A venous blood sample was obtained for analysis of inflammatory markers. The data thus obtained was statistically analyzed. RESULTS: The cases had a significant number of risk factors such as smoking, hypertension, and diabetes mellitus, previous history of CAD, increased body mass index [BMI], and raised high sensitive C-reactive protein [hs-CRP]. Patients with anterior myocardial infarction were older and had hypertension and diabetes mellitus. Patients with inferior myocardial infarction had high BMI, raised erythrocyte sedimentation rate [ESR] and alcoholism. Smokers, patients with diabetes mellitus, high total cholesterol, Low-density lipoprotein [LDL] cholesterol, and hs-CRP were more prone to complications. CONCLUSIONS: Patients with a greater number of risk factors and raised inflammatory markers were at high risk of STEMI and its complications. An approach to control the modifiable risk factors like obesity and lifestyle changes can reduce the disease burden.

Dissimilar Anxiety-like Behavior in Prepubertal and Young Adult Female Rats on Acute Exposure to Aluminium.

BACKGROUND: Puberty is a developmental transition in which an estrogenic surge occurs, mediating the release of xenoestrogens, like aluminium. Aluminium's effect on anxiety in rodents at the different developmental stages is inconsistent. AIMS: This study aimed at investigating the effect of the metalloestrogenic property of aluminium on anxiety-like behavioral changes in prepubertal and young adult female rats. OBJECTIVE: Considering this aim, our objective was to evaluate the anxiety-like behavior by the elevated plus maze in prepubertal and young adult female rats with or without acute exposure to aluminium. METHODS: To address this property of aluminium, 5mg/Kg body weight (Al-5) and 10 mg/Kg body weight (Al-10) of aluminium was administered intraperitoneally to female rats at two developmental stages, prepubertal (PP; n = 8 for each dose) and young adult (YA; n = 6 for each dose) for two weeks. Post-treatment, three days behavioral assessment of the rats was done employing elevated plus maze. RESULTS: Reduced escape latency was seen in Al-5, Al-10 pre-pubertal rats, and Al-5 young-adult rats on day 3. A significant reduction in open arm time was seen in the Al-5 young-adult rats. Aluminium treatment in the pre-pubertal rats reduced their head dipping and grooming. Reduced sniffing, head dipping, and stretch-attended posture in the treated young-adult female rats showed that they had impaired risk-taking tendency. CONCLUSION: Differential effect on the anxiety-like behavior in the pre-pubertal and young-adult female rats might be due to the metalloestrogenic property of aluminium, acting differently on the two age groups.
