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.
This study aimed to assess autonomic stress reactivity tests in type A and type B personalities using cardiovascular reflex tests.
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.
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.
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.
已发现人格类型与心血管疾病（CVD）之间存在相当大的联系。研究发现，A型和B型人格个体的自主反应均受其人格特质影响。该研究建议在更大样本量上进一步研究心脏自主功能，并使用心血管反射测试等非侵入性筛查技术来分层参与者未来患病的风险。
本研究旨在使用心血管反射测试评估A型和B型人格中的自主应激反应测试。
本研究在新德里瓦尔丹·马哈拉施特拉医学院和萨夫达容医院的生理学系进行。使用亨特 - 沃尔夫人格问卷量表从精神科识别出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。对每个受试者进行并记录自主功能测试，如握力测试、冷加压测试、深呼吸测试（DBT）、卧立位测试（LST）和瓦尔萨尔瓦动作。使用IBM SPSS Statistics for Windows 21版（2012年发布；IBM公司，美国纽约州阿蒙克）进行数据的汇编和分析。
与B型人格患者相比，A型人格患者的呼气与吸气比（E:I）和心率变化均显著降低（p = 0.000*）（分别为1.18±0.03对1.25±0.77和1.18±0.03对1.25±0.77）。与B型人格患者相比，A型人格患者的瓦尔萨尔瓦比值降低（1.38±0.10对1.48±0.18），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比值显著降低（p = 0.03*）（1.12±0.05对1.15±0.10）。握力测试和冷加压测试结果无统计学意义。
与表现出副交感神经和交感神经反应性均增加的B型人格患者相比，A型人格患者的静息心血管参数和静息自主神经张力降低。因此，为了分层参与者未来患病的风险，我们建议采用非侵入性程序，如心血管反射测试，作为一种筛查技术。
