ما المقصود بالضغط النبضي؟ ما مدى أهمية الضغط النبضي لصحتك العامة؟

إجابة من ريخا منقاد، (دكتور في الطب)

تُعرَض قراءات ضغط الدم في شكل رقمين.

  • الرقم العلوي هو الحد الأقصى للضغط الذي يبذله القلب عند الخفقان (الضغط الانقباضي).
  • والرقم السفلي هو مقدار الضغط في شرايينك بين النبضات (الضغط الانبساطي).

وتشير نتيجة طرح الرقم السفلي (الانبساطي) من الرقم العلوي (الانقباضي) إلى الضغط النبضي. على سبيل المثال، إذا كان ضغط الدم أثناء الراحة 120/‏80 ملليمترًا من الزئبق (ملم زئبقي)، فيكون الضغط النبضي هو 40، وهذا ضغط نبضي طبيعي وصحي. وبشكل عام، يكون الضغط النبضي غير صحي إذا زاد عن 40 ملم زئبقي.

قد يساعد قياس الضغط النبضي الطبيب على توقع احتمالات مخاطر الإصابة باعتلال في القلب، بما في ذلك النوبة القلبية أو السكتة الدماغية. وإذا كان الضغط النبضي أعلى من 60، يكون ذلك بمثابة عامل خطر للإصابة بمرض قلبي وعائي، وخاصةً لدى كبار السن.

ويمثل تيبس أكبر شريان في الجسم (الأورطي) السبب الرئيسي لارتفاع الضغط النبضي لدى كبار السن. ويمكن أن يؤدي ارتفاع ضغط الدم أو الترسبات الدهنية على جدران الشرايين (تصلب الشرايين) إلى تيبس شرايينك. ويُعتقد أنه كلما ارتفع الضغط النبضي، زاد تيبس الأوعية الدموية وتضررها.

وعادةً ما تؤدي معالجة ارتفاع ضغط الدم إلى تقليل الضغط النبضي. ومن المهم أيضًا اتباع نمط حياة صحي. وتتضمن الإستراتيجيات الذكية للقلب ممارسة التمارين الرياضية بانتظام وعدم التدخين والحد من تناول الكحوليات وتقليل كمية الملح في النظام الغذائي.
