Objective: In order to evaluate the role of sympathoadrenomedullary system in the causative mechanism of the anginal attack, the hemodynamic changes in heart failure were observed in 50 patients with congestive heart failure (CHF), compared to 20 normal subjects, and 20 patients with essential hypertension (HTN), all of whomhad similar lifestyles; the overall age range was 18-60 years. Hence, we compared vitaminD, parathyroid hormone (PTH), calcium, lipids, the acute phase reactant high-sensitivity C-reactive protein (hsCRP), fibrinogen, serotonin, norepinepherine (NE), and human epidermal growth factor receptor (EGF-R) between these groups. Results: This study confirms a strong association between catecholamines as well as EGF-R levels with PTH and low vitamin D levels, being related to hyperlipidemia and inflammation (hsCRP and fibrinogen) in CVD. Conclusion: This study indicates that increased levels of lipids, fibrinogen, PTH, proinflammatorymarker(s), catecholamines, and EGF-R, as well as low vitamin D, contribute to the complex process of atherosclerosis in hypertensive patients that leads eventually to CHF.
