Isolated Systolic Hypertension: Symptoms and Treatments

Written by Medicover Team and Medically Reviewed by Dr Bharath Reddy D , Cardiologist

---

Isolated systolic hypertension occurs when only the systolic blood pressure (top number) is elevated, while the diastolic remains normal. It primarily affects the cardiovascular system and is more common in older adults. Causes include arterial stiffness and aging. It increases the risk of heart disease and stroke. Treatment includes lifestyle changes and medications.

Prevalence and Demographics

ISH is more common in individuals over the age of 60 and is the most prevalent form of high blood pressure in this age group. As the population ages, the incidence of ISH is expected to rise, making it a critical public health concern.

What Are the Different Types of Isolated Systolic Hypertension?

Isolated Systolic Hypertension (ISH) is a condition where only the top number in your blood pressure reading (systolic) is high, while the bottom number (diastolic) remains normal. Often called the "silent killer," it can be classified into two main types based on its origin:

Primary ISH

• Also known as essential ISH
• No clear medical cause
• Most commonly related to aging and arterial stiffness

Secondary ISH

• Caused by an underlying health condition
• Common associated conditions include: Kidney disease, Thyroid disorders, Diabetes
• Treating the root condition can help manage ISH effectively

---

What Are the Common Causes and Risk Factors of Isolated Systolic Hypertension?

ISH develops due to a combination of natural body changes and health-related factors.

Causes

• Age-related arterial stiffness: The most common cause; arteries lose flexibility over time.
• Medical conditions: Including kidney disease, thyroid problems, and diabetes.

Risk Factors

• Age 60 and above
• Sedentary lifestyle
• High salt intake
• Low potassium levels
• Obesity
• Smoking and alcohol use
• Family history of hypertension

What Are the Isolated Systolic Hypertension Symptoms and Warning Signs?

Isolated Systolic Hypertension (ISH) usually presents no symptoms in its early stages but can lead to serious complications if left untreated.

Common Symptoms

• Morning headaches
• Dizziness or lightheadedness
• Blurred vision or occasional visual disturbances
• Shortness of breath during physical activity
• Fatigue or weak

Severe Symptoms

• Chest pain or tightness
• Irregular heartbeat
• Confusion or difficulty concentrating
• Sudden vision loss
• Fainting spells

Note: Many people with ISH may not experience noticeable symptoms, making regular blood pressure checks essential for early detection.

How Is Isolated Systolic Hypertension Diagnosed?

Early and accurate diagnosis is essential for appropriate managing of ISH.

Common Diagnostic Methods

• Regular Blood Pressure Monitoring: Multiple readings over a few days
• Ambulatory Blood Pressure Monitoring (ABPM): 24-hour tracking for a detailed view.
• Additional Tests to rule out underlying causes:
  • Blood tests: Kidney function, thyroid levels, blood sugar, and electrolytes
  • Echocardiogram: To assess heart structure and function
  • Electrocardiogram (ECG): To detect heart rhythm abnormalities

At Medicover, we use advanced diagnostic tools and individual assessments to ensure accurate detection and complete cardiovascular risk evaluation.

What Are the Treatment Options for Isolated Systolic Hypertension?

ISH treatment focuses on lowering systolic pressure while preventing complications.

Lifestyle Modifications

• Heart-healthy diet: Low in sodium, rich in fruits, vegetables, and whole grains
• Regular exercise: Brisk walking, swimming, or cycling
• Weight management
• Stop smoking and reduce alcohol

Medications (if lifestyle changes aren't enough)

• Diuretics: Help remove excess fluid
• Calcium channel blockers: Relax arteries
• ACE inhibitors: Widen blood vessels
• Beta-blockers: Slow the heart rate

At Medicover, our cardiologists create individual treatment plans combining the latest medication regimens with holistic lifestyle support to optimize blood pressure control and improve overall heart health.

• Your systolic blood pressure is consistently over 140 mmHg
• You experience symptoms like regular headaches, dizziness, or are short of breath
• You have existing conditions such as diabetes, kidney disease, or a family history of hypertension

High-Risk Groups

• Adults over 60
• Individuals with chronic diseases
• Smokers or heavy drinkers

What Is the Recovery Process After Treatment?

ISH needs long-term management, but many people live full, healthy lives with the right care.

What to Expect

• Regular blood pressure checks
• Follow-up visits to adjust treatment
• Support with diet, exercise, and lifestyle changes

Prevention

• Eat a low-salt, high-fiber diet
• Stay active and exercise regularly
• Keep your weight in a healthy range
• Avoid smoking and heavy alcohol use
• Get regular health check-ups

Possible Complications if Left Untreated
