Recent research suggests that gratitude is associated with better cardiovascular health. Here, we investigated whether trait and/or state gratitude was associated with cardiovascular responses to acute stress. Eighty-six young adults completed measures of gratitude and had their cardiovascular responses monitored throughout a standardized stress testing protocol. Trait gratitude was not associated with cardiovascular reactivity, i.e. systolic or diastolic (SBP, DBP) or heart rate (HR). However, while state gratitude was not associated with HR or DBP reactivity, it was negatively associated with SBP reactivity, such that those who reported higher state gratitude during the past week displayed lower SBP to the stressor. Moreover, this association was robust to withstand adjustment for several potential founds, such as sex, depression and body mass index. These findings are novel and highlight that gratitude, in particular state gratitude, is one potential mechanism underlying the protective benefits of gratitude on cardiovascular health.
近期研究表明，感恩与更好的心血管健康相关。在此，我们调查了特质感恩和/或状态感恩是否与对急性应激的心血管反应有关。86名年轻成年人完成了感恩测量，并在整个标准化应激测试过程中监测他们的心血管反应。特质感恩与心血管反应性无关，即与收缩压或舒张压（SBP、DBP）或心率（HR）无关。然而，虽然状态感恩与心率或舒张压反应性无关，但它与收缩压反应性呈负相关，即在过去一周报告状态感恩程度较高的人对压力源的收缩压较低。此外，这种关联在对几个潜在因素（如性别、抑郁和体重指数）进行调整后依然稳健。这些发现是新颖的，并突出表明感恩，尤其是状态感恩，是感恩对心血管健康产生保护作用的一种潜在机制。
