背景:已经看到人格类型与心血管疾病(CVD)之间存在相当大的联系。发现A型和B型人格个体的自主反应都受到其人格特质的影响。该研究建议在更大的样本量中进一步研究心脏自主神经功能,并使用非侵入性筛查技术,如心血管反射测试,对参与者未来疾病的风险进行分层。
目的:本研究旨在使用心血管反射测试评估A型和B型人格的自主神经应激反应性测试。
方法:这项研究是在生理学系进行的,VardhmanMahavir医学院和Safdarjung医院,新德里。Hunter-Wolf人格问卷量表用于确定60名成年人,其中30人被归类为A型人格,30人被归类为B型人格,从精神科.自主功能测试,如手握测试,冷压缩机试验,深呼吸测试(DBT)躺到站立测试(LST),和瓦尔萨尔瓦演习,进行并记录每个受试者。IBMSPSSStatisticsforWindows,版本21(2012年发布;IBMCorp.,Armonk,纽约,美国)用于数据的汇编和分析。
结果:与B型人格患者相比,A型人格患者的E:I(呼气到吸气)比率和δ心率均显着降低(p=0.000*)患者(1.18±0.03对1.25±0.77和1.18±0.03对1.25±0.77)。与B型人格患者(1.48±0.18)相比,A型人格患者的Valsalva比率降低(1.38±0.10),具有统计学意义(p=0.001*)。与B型人格患者相比,A型人格患者的30:15比率显着降低(p=0.03*)(1.12±0.05对1.15±0.10)。手握测试和冷加压测试结果在统计学上无统计学意义。
结论:与B型人格患者相比,表现出副交感神经和交感神经反应的增加,A型人格患者静息心血管参数和静息自主神经张力降低。因此,为了对参与者未来患病的风险进行分层,我们建议采用非侵入性程序,比如心血管反射测试,作为一种筛选技术。
BACKGROUND: A considerable link between personality types and cardiovascular diseases (CVDs) has been seen. Autonomic responses in both type A and type B personality individuals were found to be influenced by their personality traits. The study suggests further research on cardiac autonomic functions in larger sample sizes and the use of non-invasive screening techniques like cardiovascular reflex tests to stratify participants\' risk of future illness.
OBJECTIVE: This study aimed to assess autonomic stress reactivity tests in type A and type B personalities using cardiovascular reflex tests.
METHODS: This study was conducted at the Department of Physiology, Vardhman Mahavir Medical College and Safdarjung Hospital, New Delhi. The Hunter-Wolf Personality Questionnaire Scale was used to identify 60 adults, 30 of whom were classified to have type A personality and 30 have type B personality, from the psychiatry department. Autonomic function tests, such as the handgrip tests, cold pressor test, deep breathing test (DBT), lying-to-standing test (LST), and Valsalva maneuver, were performed and recorded for each subject. IBM SPSS Statistics for Windows, version 21 (released 2012; IBM Corp., Armonk, New York, United States) was used for the compilation and analysis of data.
RESULTS: The E:I (expiration-to-inspiration) ratio and delta heart rate of the type A personality patients both significantly decreased (p = 0.000*) as compared to the type B personality patients (1.18 ± 0.03 versus 1.25 ± 0.77 and 1.18 ± 0.03 versus 1.25 ± 0.77). The Valsalva ratio of the type A personality patients decreased (1.38 ± 0.10) as compared to the type B personality patients (1.48 ± 0.18), which was statistically significant (p = 0.001*). The 30:15 ratio in the type A personality patients was significantly decreased (p = 0.03*) compared to the type B personality patients (1.12 ± 0.05 versus 1.15 ± 0.10). The handgrip test and cold pressor test results were statistically insignificant.
CONCLUSIONS: Compared to the type B personality patients, which exhibited an increase in both parasympathetic and sympathetic reactivity, the type A personality patients exhibited a reduction in resting cardiovascular parameters and resting autonomic tone. Consequently, in order to stratify the participants\' risk of future illness, we recommend employing non-invasive procedures, such as cardiovascular reflex tests, as a screening technique.
