A Cardiologist Warns: These 5 Medications May Increase the Risk of Heart Attack and Stroke in Older People

As we get older, taking care of our heart becomes increasingly important. Many people over the age of 60 take medications every day to manage pain, blood pressure, arthritis, or other chronic conditions.

Although medications can be essential for maintaining good health, certain drugs may also increase cardiovascular risks when used incorrectly, taken for too long, or combined with other medications.

Some common medications can raise blood pressure, cause fluid retention, increase bleeding risk, or interfere with treatments that protect the heart.

The important message is not to stop taking your medication, but to understand its potential risks and discuss safer options with your healthcare professional.

Here are five medication categories that deserve particular attention in older adults.

1. Ibuprofen and Other Anti-Inflammatory Painkillers

Ibuprofen, naproxen, and other nonsteroidal anti-inflammatory drugs (NSAIDs) are commonly used to relieve arthritis, muscle pain, headaches, and inflammation.

However, these medications may increase cardiovascular risks, especially when taken regularly or at high doses.

They can:

• Raise blood pressure.
• Cause the body to retain sodium and water.
• Place additional strain on the heart.
• Affect kidney function.
• Increase the risk of cardiovascular complications in susceptible individuals.

For older adults with high blood pressure, kidney disease, or heart failure, these medications require particular caution.

Occasional use may be appropriate for some people, but long-term use should be reviewed by a healthcare professional.

2. Certain Medications That Increase Bleeding Risk

Some medications used to prevent blood clots can increase the risk of serious bleeding.

Examples include anticoagulants and certain antiplatelet medications.

These drugs are often prescribed to people with conditions such as atrial fibrillation or a history of blood clots.

Although they can help prevent dangerous strokes, they may also increase the risk of bleeding, particularly in older adults.

The balance between preventing blood clots and avoiding bleeding depends on the individual’s medical history, kidney function, age, and other medications.

Never stop an anticoagulant or antiplatelet medication without medical advice.

For many patients, these medications provide important protection against heart attack or stroke.

3. Certain Blood Pressure Medications That Can Cause Dizziness

Some medications used to treat high blood pressure can cause blood pressure to fall too much when a person stands up.

This condition is called orthostatic hypotension.

It can cause:

• Dizziness.
• Weakness.
• Blurred vision.
• Fainting.
• Falls.

Older adults may be particularly vulnerable because of changes in circulation, dehydration, and the use of multiple medications.

Examples of medications that may contribute include certain alpha-blockers, such as doxazosin and prazosin, and some centrally acting blood pressure medications.

However, these medications may still be appropriate for specific patients.

The goal is to maintain blood pressure control while avoiding excessive drops that could lead to falls or other complications.

4. Certain Heart Rhythm Medications

Medications used to control abnormal heart rhythms can be essential for protecting patients from dangerous cardiovascular complications.

However, some antiarrhythmic drugs may worsen certain underlying heart conditions or cause additional rhythm problems.

Examples include certain medications such as flecainide, sotalol, and dronedarone.

Their risks depend on the patient’s specific heart condition, kidney function, and other medications.

For example, some antiarrhythmic medications may be unsuitable for people with certain forms of heart failure.

These medications should only be adjusted under medical supervision.

5. Aspirin Taken Daily Without a Clear Medical Reason

Low-dose aspirin is sometimes prescribed to help prevent blood clots.

For people who have already experienced a heart attack, certain strokes, or other cardiovascular events, aspirin may provide important protection.

However, the situation is different for older adults who take aspirin solely to prevent their first heart attack or stroke.

In some people aged 70 and older, the risk of serious bleeding may outweigh the potential cardiovascular benefit.

This is particularly important for people who have:

• A history of stomach ulcers.
• Previous gastrointestinal bleeding.
• Other medications that increase bleeding risk.
• Certain kidney or liver conditions.

Aspirin should not automatically be started as a preventive treatment simply because someone is getting older.

Anyone already taking aspirin should discuss the reason for treatment with their healthcare professional before making changes.

Why Older Adults Need Extra Medication Precautions

As people age, the body may process medications differently.

Kidney function can decline, medications may remain in the body longer, and sensitivity to certain drugs may increase.

Taking several medications simultaneously can also increase the possibility of interactions.

This is why regular medication reviews are particularly important for older adults.

A healthcare professional or pharmacist can evaluate:

• Whether each medication is still necessary.
• Whether the dosage is appropriate.
• Whether two medications interact.
• Whether safer alternatives are available.
• Whether blood pressure and kidney function need monitoring.

Warning Signs That Should Never Be Ignored

Some cardiovascular symptoms require immediate medical attention.

Call emergency services if someone experiences:

• Chest pain, pressure, or tightness.
• Sudden difficulty breathing.
• Sudden weakness or numbness on one side of the body.
• Difficulty speaking or understanding speech.
• Sudden vision changes.
• Fainting accompanied by concerning symptoms.

These symptoms may indicate a heart attack, stroke, or another serious medical condition.

Do not wait for symptoms to disappear before seeking help.

How to Protect Your Heart While Taking Medication

The safest approach is to use medications carefully and maintain regular communication with your healthcare professional.

Consider these practical steps:

1. Keep an updated list of all medications and supplements.
2. Take medications exactly as prescribed.
3. Avoid combining painkillers without checking their ingredients.
4. Monitor blood pressure when recommended.
5. Ask whether regular kidney function tests are necessary.
6. Discuss dizziness, swelling, or unusual bleeding promptly.
7. Review your medications regularly, especially after hospital visits or changes in health.

Final Thoughts

Medications can play an essential role in preventing heart attacks, strokes, and other serious conditions.

However, certain painkillers, blood pressure medications, heart rhythm drugs, and blood-thinning treatments may carry additional risks for older adults.

The key is understanding that medication safety depends on the individual.

Never stop taking prescribed medication because of a general warning online.

Instead, speak with your doctor or pharmacist about your personal risks, the benefits of your treatment, and whether any adjustments are appropriate.

A regular medication review can help older adults protect their heart, reduce avoidable complications, and maintain a better quality of life.
