    高血压朋友有没有发现血压越测越高呢？那么血压反复测量血压越测越高是怎么回事呢？

 

    曾有一位七十多岁老先生连续两次夜间看急诊，都是因为血压高。但来院后测量血压均为150/80 mmHg左右。追问病史，得知老先生为高血压患者，平时血压控制满意。数日前夜间11点多，老先生自觉头晕不适，自己测量血压为160/90 mmHg，再次测量为170/100 mmHg，几分钟后再测为180/100 mmHg。自己服用降压药物半小时后血压下降至150/70 mmHg左右。自此以后，每天晚上11点多老先生均为自己测血压，每次测量血压均增高，并且连续测量时一次比一次高。患者住院后进行动态血压监测，结果显示其血压控制良好。这位患者的血压波动显然是由于精神紧张所致。因为他担心夜间血压增高，在紧张的情绪下测血压肯定会较高，第一次发现血压增高后精神更紧张，再次测量血压进一步升高。

 

    这个病例告诉我们，虽然鼓励高血压患者自己在家中测量血压，但不要过于频繁的测量，以免导致不必要的紧张并使血压更加升高。

 

    那么，高血压患者应该多长时间测量一次血压？一般来讲，在接受药物治疗初期或调整降压药物过程中，每天测量2-3次为宜（如早晚或早中晚各测量一次）。过于频繁的自测血压容易影响测量准确性，甚至导致血压明显升高。病情稳定且治疗方案固定的患者，每周测量1-2天，每天早晚各测一次即可。每次测量后均要记录下来，再次就诊时由医生参考，以便了解其血压控制情况。

\"高血压喝点酒好吗\" 

长期过量饮酒是高血压、心血管病发生的危险因素。饮酒还可对抗降压药的作用，使血压不易控制，戒酒后，除血压下降外，降压药的疗效也大为改善。尽管有报道少量饮酒可能减少冠心病发病的危险，但少量饮酒的定义不同，不同饮酒量与健康的关系很难达成共识，故不提倡少量饮酒预防冠心病，故高血压患者最好不饮酒。

高血压如何引起动脉硬化，高血压和动脉硬化又是怎么形成的呢，

\"高血压如何引起动脉硬化\"

我们的动脉血管分三层：内膜、中层、外膜（如上图），血液里都有胆固醇，如果胆固醇进入血管内膜下面，逐渐积累，就形成了动脉粥样斑块，血管腔就会越来越狭窄，引起相应部位组织器官（如心脏、脑等）的缺血。这就是冠心病、脑梗死的发病机制（如下图）

 \"高血压如何引起动脉硬化\"

健康人的血管内膜是很严密的，胆固醇很难进入。那么，为啥有人会发生动脉粥样硬化斑块呢？这里打个比方：如果动脉粥样斑块是一碗粥，胆固醇就是熬粥用的米。只有米没有火也不能熬粥。火在哪儿？高血压、糖尿病、吸烟就是火！

 

单说高血压。所谓高血压，就是血管里面血流的压力增高了。比如正常情况下血管里面的压力只有120mmHg，高血压病人血管内的压力可以增高到140mmHg以上，甚至会高达200mmHg。这么高的压力，就会把动脉血管内膜损坏。血管内膜损坏、出现小裂口后，胆固醇就会轻松进入血管内膜和血管中层之间了。有火、有米，这碗粥就熬成了。

 

所以说，高血压病人只控制血压是不够的，还要控制胆固醇。高血脂病人只是降血脂也是不够的，还要好好控制血压。一边断粮，一边灭火，还能熬成粥吗？道理就是这么简单。

对于成年人，每个人都要了解自己的血压水平，每年都要测几次血压。那么量血压时候是电子血压计好还是水银血压计好？

 \"电子血压计好还是水银血压计好\"

现在越来越多的医疗机构开始应用电子血压计。很多人以为电子血压计不准，这种观点是错误的。电子血压计不仅值得信赖，而且今后将逐渐取代传统的水银血压计。无论是我国的高血压指南，还是近年来先后更新的欧美高血压指南都充分肯定了电子血压计的临床地位。

 

例如，加拿大高血压指南是这样说：

1. 测量血压首选电子血压计，而非传统的听诊法；

2. 应用电子血压计在家中自己测量血压时，血压平均值≥135/85 mmHg时可诊断为高血压；

3. 应用电子血压计在家中自行测量血压的数据可以作为诊断高血压的依据。

 

我国高血压指南也充分肯定了电子血压计的重要地位与可靠性。由此可见，电子血压计是值得信赖的。但要选择符合计量标准的电子血压计，并掌握正确的测量血压的方法。

 

近年来，电子血压计的应用越来越多。除家庭应用外，很多医院也开始用电子血压计取代水银柱血压计。2013年我国签署了水俣公约，按照该公约要求，至2020年我国将停止生产水银柱血压计，因此电子血压计将会成为血压测量的主要工具。

 

很多人认为电子血压计不准确，这种观点是错误的。只要所购买的电子血压计经过了国际标准验证（购买时要认真查看说明书），其准确性是可以信赖的。若不放心的话，购买电子血压计后可与水银柱血压计进行对比（建议去大医院对比，因为大型公立医院的水银柱血压计每年都要强制进行标准化计量检测，所以更可靠）。需要说明的是，目前只推荐选用臂式电子血压计，在手腕测量血压的腕式血压计的准确性尚有待评估，因此不建议选用。

 

有人说，我在家测量的血压跟在医院测的数值不一样，是不是说明我的血压计不准？不是，只要你测血压的方法正确，你自己测得血压比医生测量的数值更能反映你的真实血压。在医院测血压会发生“白大衣现象”，导致血压比实际血压偏高。在家自己测血压不会出现这种情况，因而更可靠。还有一种可能，就是血压一直在变。我们每个人的血压都一直在波动，每天上下相差30-40mmHg是经常的事儿，上午140/90，到了下午就可能是120/80。所以你在家测血压和在医院测血压完全可能不一样。

 

其实吧，即便用同一个血压计，每隔几分钟测一次，每次跟每次测量的数值也不一样，不信你试试？这不是因为血压计不准，是因为我们的血压一直在变化。

 

与水银柱血压计相比，电子血压计对测量技术要求低，使用简便，且可避免人为误差。但是患房颤或频发早搏的患者，使用电子血压计测量可能会有较大误差。这种情况下最好多测几次、取平均值，或者选用水银柱血压计测量。

 

所以说，电子血压计是值得信赖的，特别适用于在家中自己测量血压。有人说电子血压计不准，这是一个错误观念。

无论冠心病心肌梗死还是脑梗死、脑出血，本质上都属于血管疾病。这类疾病的共同病理基础是因动脉粥样硬化斑块所致的血管病变。如何使血管更有弹性更健康，让血管弹性健康对于维护生命健康至关重要。没有弹性健康的血管，就没有健康的心脑肾。维护弹性健康的血管，要注意以下几个方面：

 \"如何使血管更有弹性更健康\"

1. 危害血管弹性健康的第一元凶就是胆固醇。血液中胆固醇增高可以显著增加形成动脉粥样斑块的风险。正因如此，近年来我们越来越重视对胆固醇的干预。降低血液中胆固醇的水平、减少形成粥样斑块的原料，动脉内就不容易形成斑块，也就难以发生心梗和脑梗。

 

2. 高血压、糖尿病、吸烟、精神紧张等均会破坏动脉内膜，为胆固醇进入血管壁内提供帮助，进而增加动脉粥样斑块形成的风险。因此有上述危险因素者一定要积极纠正。

 

3. 每位成年人每年都要测血压，最好每年测一次血脂血糖，这样能够及时发现高血压、糖尿病与高胆固醇血症，并及时接受治疗。轻度的血压、血脂、血糖增高一般没有明显症状，倘若出现了明显症状往往提示病情较重，这时治疗效果就会变差，因此经常筛查、早期干预这些危险因素是维护血管弹性健康的重要举措。

 

4. 虽然控制饮食、增加运动是预防心血管疾病的基石，但对于确诊高血压、糖尿病与高胆固醇血症患者，常常需要药物治疗，并且要长期坚持治疗。倘若您已经存在这些疾病，不要犹豫，一定在医生指导下积极治疗，这样能为自己的血管健康提供保障。目前没有任何保健品能够预防心脑血管疾病，不要迷信广告产品、传销产品、美国产品、新西兰产品、纯中药制剂、祖传秘方、“专门清除血管垃圾”的保健食品等等，这些都没有真正疗效。

血压偶尔升高需要吃药吗？要紧吗？


这要视情况而定。如果每天的血压多次测量均在正常范围，只是偶有一两次运动后、情绪激动时增高，这是正常情况，不要紧，也不需要治疗。如果多次测量都高，那么就应该到医院咨询医生了。如果平时都正常，偶尔一天增高，不要着急，过几天再次测量，若仍然高就应该咨询医生了。需要注意的是，间断性血压升高有可能是高血压前期的表现，如果不注意预防，很可能发展为持续性高血压。

 

每个人的血压每时每刻都在波动，这个波动受到血压的内在变化规律、外界环境因素以及测量血压时的测量误差三个方面的影响。兴奋、恐惧和运动时血压增大，当兴奋紧张的情绪消失或者停止运动后血压又迅速下降；睡眠时血压会降低，而醒来时下降的血压又会立即回升；环境温度下降则血压升高，环境温度升高则血压又降低。此外，血压还可受吸烟、饮酒、饮咖啡等因素影响而引起一时性变化。人体血压之所以不断波动，是为了更好地适应机体内部与外部环境的变化。所以说血压在一定范围内波动是正常现象。正因如此，如果连续测量血压，很多人的血压都会偶有超过140/90 mmHg的情况，所以这是一种正常现象。然而，如果一天之内很多次血压测量结果高于正常，那就不正常了。

 \"血压偶尔升高需要吃药吗\"

临床上，有一种连续测量血压的技术方法，称作“动态血压监测”，用这种方法可以连续记录24小时的血压（每半小时至1小时测量一次血压）。动态血压检测结果中有一个参数叫做“动态血压负荷值”，该指标反映的是每天24小时内所测得的血压数值有多少次达到高血压的诊断标准。例如，某人的动态血压负荷是20%，就意味着在每天40次血压测量结果中有8次超过了140/90 mmHg（8÷40=20%）。动态血压负荷值越高，诊断高血压的可能性就越大。

 

一般而言，健康成年人的动态血压负荷值应该＜15%。动态血压负荷值≥50%（即半数血压测量值均超过140/90 mmHg）可作为高血压的参考诊断标准。有研究显示，如果动态血压负荷值超过40%，发生脑血管病的风险就已明显增高。所以，在不发生低血压的前提下，血压负荷值越低越好。实际上，动态血压监测所得到的血压数值比在医院用台式血压计所测得的血压数值要低一些。如果24小时动态血压平均值超过130/80 mmHg、或者日间血压平均值超过135/85 mmHg，就应该考虑诊断高血压了。

研究者对12708位18~76岁的西班牙裔和拉美裔美国人的晚餐情况进行了分析，判断晚餐吃得多少与血压、血糖等的关系。

 

这项研究以晚餐摄入的能量占全天摄入总能量的比例为标准来定义晚餐吃得多还是少，大于30%为多。

 

结果显示，与晚餐吃得少的人相比，那些在晚上6点以后，晚餐带来的能量至少为30%的人，得高血压的风险增加了23%，得糖尿病前期的风险增加了19%。

 

具体，晚餐吃得多的人空腹血糖明显升高（93. 7 mg/dL vs 93.0 mg/dL）、收缩压（118.7 mmHg vs 117.5 mmHg）、舒张压（72.2 mmHg vs 71.0 mmHg）也明显更高。

 

进一步分析显示，晚上6点后，每多摄入总能量的1%，空腹血糖、胰岛素水平以及胰岛素抵抗均会“水涨船高”。

 

研究者指出，“在给患者生活方式建议时，我们经常会建议吃多少或吃什么，其实还应该考虑一下什么时候吃。晚餐应该早吃点”。

 

其实对于晚餐时间的重视，在去年美国心脏协会发表的一项声明中就可见一斑。

 

声明指出，在保证早餐的情况下，对自己什么时候吃饭，具体吃什么要“精打细算”一下，并且尽量不要太晚进餐，或会有助于降低心血管病风险。

 

进餐时间之所以会影响健康，可能是由于其对身体生物钟产生的影响所致。在动物实验中，如果在睡觉等不活动时段进食，其生物钟会重设，从而改变营养代谢，导致体重的更多增加，胰岛素抵抗以及炎症。
