Blood pressure

Hello, Dr.
Zhong! My blood pressure is 125/98, and it seems that my diastolic pressure is too high? I read in a medical reference book that a high diastolic pressure is more dangerous than a high systolic pressure, as it may indicate issues with other organs.
Why is that? Additionally, my pulse rate frequently ranges between 100-110, which also seems abnormal.
What conditions could cause a rapid pulse? Thank you!

Hello, Frj: Approximately 90% of hypertension is classified as essential hypertension, which is often of unknown origin and may be related to genetics.
Additionally, about 5% to 10% of cases can be attributed to identifiable causes, known as secondary hypertension, which may arise from conditions affecting the kidneys, adrenal glands, or thyroid.
Elevated diastolic blood pressure can lead to vascular stiffness, increasing the risk of thrombosis or rupture in the blood vessels of vital organs such as the heart, kidneys, and brain, resulting in complications.
The pulse reflects heart rate; a rate exceeding 100 beats per minute is considered abnormal.
It is important to investigate the underlying causes, such as anemia, pregnancy, or hyperthyroidism, and consult with an internist or cardiologist for evaluation and treatment.
Best wishes for your health from Dr.

More Info

High diastolic blood pressure (DBP) and elevated heart rate (tachycardia) can be significant indicators of underlying cardiovascular issues and other health concerns. Your reported blood pressure of 125/98 mmHg indicates that your diastolic pressure is indeed elevated, as a normal DBP is typically below 80 mmHg. The concern regarding high diastolic pressure is valid, as it can lead to various complications.

Understanding Diastolic Blood Pressure
Diastolic blood pressure is the pressure in your arteries when your heart rests between beats. It reflects the minimum pressure exerted on the arterial walls and is crucial for assessing overall cardiovascular health. Elevated diastolic pressure can lead to increased workload on the heart and may contribute to conditions such as left ventricular hypertrophy, heart failure, and increased risk of cardiovascular events like stroke or heart attack.

The reason high diastolic pressure is often considered more dangerous than high systolic pressure (the top number in a blood pressure reading) is that it can indicate increased resistance in the arteries. This resistance can be due to various factors, including arterial stiffness, atherosclerosis, or other vascular diseases. Over time, elevated DBP can lead to damage in vital organs such as the heart, kidneys, and brain, potentially resulting in complications like chronic kidney disease or cognitive decline.

Elevated Heart Rate
Your heart rate of 100-110 beats per minute is classified as tachycardia, which is generally defined as a resting heart rate above 100 beats per minute. Tachycardia can be caused by a variety of factors, including:
1. Anxiety or Stress: Emotional stress can lead to increased heart rate.

2. Physical Activity: Exercise or physical exertion naturally raises heart rate.

3. Fever or Infection: The body’s response to infection often includes an elevated heart rate.

4. Anemia: A lower red blood cell count can lead to increased heart rate as the heart works harder to deliver oxygen.

5. Hyperthyroidism: An overactive thyroid can increase metabolism and heart rate.

6. Caffeine or Stimulants: Consumption of caffeine or other stimulants can lead to temporary increases in heart rate.

7. Heart Conditions: Certain heart conditions, such as arrhythmias or heart failure, can also cause tachycardia.

Recommendations
Given your elevated diastolic blood pressure and heart rate, it is essential to consult with a healthcare professional for a comprehensive evaluation. They may recommend:
- Lifestyle Modifications: This includes dietary changes (such as reducing salt intake), regular physical activity, weight management, and stress reduction techniques.

- Monitoring: Regular monitoring of blood pressure and heart rate can help track changes and assess the effectiveness of any interventions.

- Diagnostic Tests: Depending on your overall health and symptoms, your doctor may suggest further tests, such as blood tests, an electrocardiogram (ECG), or echocardiography, to evaluate heart function and rule out any underlying conditions.

Conclusion
In summary, high diastolic blood pressure and elevated heart rate are important health indicators that warrant attention. They can signify potential cardiovascular risks and other health issues. It is crucial to work closely with your healthcare provider to determine the underlying causes and develop an appropriate management plan tailored to your specific needs. Regular follow-ups and proactive health management can significantly reduce the risk of complications associated with these conditions.
