The present research investigated the effects of two different types of music on cardiovascular responses in essential hypertensive men in comparison with healthy men based on introversion and extraversion.
One hundred and thirteen hypertensive men referred to Madani Heart Hospital in Tabriz completed the NEO-FFI Questionnaire and after obtaining acceptable scores were classified in four groups: introvert patients, extravert patients, introvert healthy subjects, and extravert healthy subjects (each group with 25 samples with age range 31-50). Baseline blood pressure and heart rate of each subject was recorded without any stimulus. Then subjects were exposed to slow-beat music and blood pressure and heart rate were recorded. After15 minute break, and a little cognitive task for distraction, subjects were exposed to fast-beat music and blood pressure and heart rate were recorded again.
Multivariate analysis of covariance (MANCOVA) test showed that extravert patient subjects obtained greater reduction in systolic blood pressure and heart rate after presenting slow-beat music compared with introvert patients (P= 0.035, and P= 0.033 respectively). And extravert healthy subjects obtained greater reduction in heart rate after presenting slow-beat music compared with introvert healthy subjects (P= 0.036). However, there are no significant differences between introvert and extravert groups in systolic and diastolic blood pressure and heart rate after presenting fast-beat music.
Based on our results, introvert subjects experience negative emotions more than extravert subjects and negative emotions cause less change in blood pressure in these subjects compared with extravert subjects.
本研究调查了两种不同类型的音乐对原发性高血压男性心血管反应的影响，并与基于内向和外向性格的健康男性进行比较。
113名转诊至大不里士马丹尼心脏医院的高血压男性完成了NEO-FFI问卷，在获得可接受分数后被分为四组：内向型患者、外向型患者、内向型健康受试者和外向型健康受试者（每组25个样本，年龄范围31-50岁）。在没有任何刺激的情况下记录每个受试者的基线血压和心率。然后让受试者接触慢节奏音乐，并记录血压和心率。休息15分钟并进行一些认知任务以分散注意力后，让受试者接触快节奏音乐，并再次记录血压和心率。
多变量协方差分析（MANCOVA）测试表明，与内向型患者相比，外向型患者在听慢节奏音乐后收缩压和心率的降低幅度更大（分别为P = 0.035和P = 0.033）。与内向型健康受试者相比，外向型健康受试者在听慢节奏音乐后心率的降低幅度更大（P = 0.036）。然而，在听快节奏音乐后，内向型和外向型组在收缩压、舒张压和心率方面没有显著差异。
根据我们的研究结果，内向型受试者比外向型受试者更容易体验到负面情绪，并且与外向型受试者相比，负面情绪在这些受试者中引起的血压变化更小。
