患有心血管疾病 (CVD) 的兄弟姐妹显著增加了你晚年患心血管疾病的风险. 即使考虑到其他已知的风险因素和父母心血管疾病病史,这种风险仍然存在.
科学领域:
- 心血管疾病流行病学
- 心血管疾病的遗传学
- 风险因素分析 风险因素分析
背景情况:
- 众所周知,父母的心血管疾病 (CVD) 会使后代的风险增加一倍.
- 兄弟CVD对后代CVD风险的影响尚未得到充分证实.
- 了解家族风险对于预防策略至关重要.
研究的目的:
- 调查兄弟CVD是否独立地预测中年成人中发生的CVD.
- 量化与兄弟CVD相关的风险,根据已确定的风险因素进行调整.
- 为了比较兄弟CVD与父母CVD的独立风险.
主要方法:
- 利用了来自弗雷明汉子女研究队列 (n=2475) 的数据.
- 随访了30岁以上的参与者8年,不包括那些事先患有心血管疾病的人.
- 雇员组合后勤回归来评估兄弟心血管疾病和8年心血管疾病风险之间的关联.
主要成果:
- 风险因子调整后,同胞心血管疾病与发生心血管疾病的风险显著增加有关 (OR,1.45;95% CI,1.10-1.91).
- 在子集分析中,兄弟CVD比父母CVD (OR,1.45) 具有更高的风险 (OR,1.99).
- 即使考虑到父母心血管疾病史,这种关联仍然很重要.
结论:
- 兄弟心血管疾病是中年成年人未来心血管事件的独立预测因素.
- 兄弟CVD所带来的风险超过了既定的风险因素和父母CVD所带来的风险.
- 包括兄弟姐妹在内的家族病史是评估心血管风险的关键组成部分.

Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
