Impact of major earthquakes on the incidence of acute coronary syndromes - A systematic review of the literature. Hellenic J Cardiol 2018; 59:262-267. [PMID: 29807192 DOI: 10.1016/j.hjc.2018.05.005] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2018] [Revised: 05/11/2018] [Accepted: 05/18/2018] [Indexed: 01/13/2023] Open
Abstract
Natural disasters such as tsunami, hurricanes, and earthquakes may have a negative impact on cardiac health. The aim of our systematic review is to evaluate the impact of earthquakes on the incidence of acute coronary syndromes and cardiac mortality and to examine the impact of the time of earthquakes on the incidence of acute coronary syndromes. MEDLINE and Cochrane databases were searched for studies assessing the impact of earthquakes on acute coronary syndromes from inception until December 20, 2017. Reference lists of all included studies and relevant review studies were also searched. A total of 26 studies on 12 earthquake disasters were included in the systematic review. The existing data show a significant negative impact of the Great East Japan, Christchurch, Niigata-Chuetsu, Northridge, Great Hanshin-Awaji, Sichuan, Athens, Armenia, and Noto Peninsula earthquakes on the incidence of acute coronary syndromes. By contrast, studies on the Newcastle, Loma Prieta, and Thessaloniki earthquakes did not show a significant correlation with myocardial infarction and cardiac mortality. In conclusion, earthquakes may be associated with increased incidence of acute coronary syndromes and cardiovascular mortality. There are conflicting data about the impact of the timing of earthquakes on the occurrence of acute coronary syndromes. Preventive measures to promote the adjustment of healthcare systems to treat cardiovascular diseases after natural disasters should be immediately implemented particularly in high-risk regions.

Effects of oral paricalcitol therapy on arterial stiffness and osteopontin in hypertensive patients with chronic kidney disease and secondary hyperparathyroidism. Hellenic J Cardiol 2018; 60:108-113. [PMID: 29305902 DOI: 10.1016/j.hjc.2017.12.010] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2017] [Revised: 12/22/2017] [Accepted: 12/28/2017] [Indexed: 12/26/2022] Open
Abstract
BACKGROUND Arterial stiffness is linked to the progression of atherosclerosis, while activation of vitamin D receptor exerts favorable cardiovascular effects in patients with renal insufficiency. In this study, we investigated the effects of oral treatment with paricalcitol, a potent vitamin D receptor activator, on arterial stiffness and osteopontin, a marker of atherosclerosis, in hypertensive patients with chronic kidney disease (CKD) and secondary hyperparathyroidism. METHODS We followed up 29 treated hypertensive patients (mean age: 74.1 years, 19 men, office blood pressure = 132/85 mmHg) with CKD stages 3-5 (mean glomerular filtration rate [GFR] = 19.4 ml/min/1.73 m2) who were on therapy with oral paricalcitol for 1 year. The control group consisted of 10 age-, sex-, and GFR-matched hypertensive patients with secondary hyperparathyroidism. RESULTS After 1 year of treatment with paricalcitol compared to baseline, there was no statistical difference in levels of GFR, office blood pressure, and osteopontin (p = NS for all), while carotid-femoral PWV was reduced from 11.8 ± 2.6 m/s to 11.2 ± 2.4 m/s (p < 0.05). The control group exhibited no significant changes in carotid-femoral PWV (p = NS). CONCLUSIONS Treatment with oral paricalcitol in hypertensive subjects suffering from CKD stages 3-5 and secondary hyperparathyroidism is accompanied by amelioration of arterial stiffness as reflected by the reduction of carotid-femoral PWV.
