How High Is Too High For Blood Pressure? Cardiologist Explains
TLDRIn this episode of 'Talking with Docs,' Dr. Brad Weiner, Dr. Paul Zalzel, and Mike Heffernan discuss the importance of blood pressure and its impact on health. They explain that a normal blood pressure is 120 over 80, with the first number (systolic) representing the peak pressure when the heart contracts, and the second number (diastolic) being the resting pressure. Concerns arise when blood pressure is consistently above 130/80, and lifestyle modifications are recommended before medication. High blood pressure can lead to serious health issues such as kidney failure, stroke, and heart attack. The doctors encourage home monitoring of blood pressure to account for 'white coat hypertension,' where readings are higher in a clinical setting due to anxiety. They emphasize that both systolic and diastolic pressures are crucial and that individuals should take charge of their health and blood pressure management.
Takeaways
- 📈 A normal blood pressure reading is 120 over 80, which is considered optimal.
- 💓 The '120' in the blood pressure reading is the systolic pressure, representing the peak pressure when the heart beats.
- 🛑 The '80' is the diastolic pressure, which is the resting pressure when the heart is at rest between beats.
- 🚨 Concerns arise when blood pressure readings are between 130 and 140 over 90.
- 💊 In Canada, a reading above 140 over 90 in the office setting is when medication is considered.
- 🍽️ Lifestyle modifications are recommended before resorting to medication to lower blood pressure.
- 🧠 High blood pressure can damage organs like the brain and kidneys, potentially leading to stroke and kidney failure.
- 🫀 High blood pressure can also result in heart attacks due to the strain on the coronary arteries.
- 🤔 Both systolic and diastolic pressures are important; neither is considered more important than the other.
- 🏠 Doctors encourage patients to monitor their blood pressure at home to account for 'white coat hypertension'.
- 📚 Home blood pressure readings can provide a more accurate picture of a person's blood pressure as it is not influenced by the stress of a clinical setting.
Q & A
What is the optimal blood pressure according to the video?
-The optimal blood pressure is 120 over 80, which is considered normal.
What does the first number in the blood pressure reading represent?
-The first number, or systolic pressure, represents the peak pressure when the heart squeezes the blood out during each heartbeat.
What does the second number in the blood pressure reading represent?
-The second number, or diastolic pressure, represents the resting pressure when the heart is at rest and the aortic valve is closed.
What is the significance of a blood pressure reading of 120 over 80?
-A blood pressure of 120 over 80 indicates that the pressure is not too high or too low, which is optimal for efficiently circulating blood through the body without causing strain on the organs.
At what blood pressure level do doctors start to become concerned?
-Doctors start to become concerned when the blood pressure is between 130 and 140 over 80.
What blood pressure level typically prompts consideration for medication?
-A value in the office above 140 over 90 typically prompts consideration for medication, although lifestyle modifications are always the first approach.
Why is high blood pressure a problem for the body?
-High blood pressure is a problem because it can cause damage to vital organs like the brain and kidneys by exerting constant high pressure against them, which can lead to conditions like stroke, heart attack, and kidney failure.
What is 'white coat hypertension'?
-White coat hypertension is a phenomenon where a patient's blood pressure is elevated in a clinical setting due to anxiety, but normal when measured at home.
Why is it recommended for patients to monitor their blood pressure at home?
-Monitoring blood pressure at home helps account for the possibility of white coat hypertension and provides a more accurate representation of a patient's typical blood pressure levels.
Which component of blood pressure, systolic or diastolic, is more important?
-Both systolic and diastolic pressures are important, and high readings in either can indicate potential health issues.
What is the term for the waveform of blood pressure due to the heart's contractions and expansions?
-The waveform of blood pressure is referred to as the pulsatile flow, which includes a peak (systolic) and a trough (diastolic).
How can lifestyle modifications help in managing blood pressure?
-Lifestyle modifications such as diet, exercise, stress management, and avoiding tobacco and excessive alcohol can help lower blood pressure without the need for medication.

📚 Understanding Blood Pressure Basics
In this paragraph, the doctors explain the fundamentals of blood pressure, including what the numbers represent and what is considered normal. They clarify that a normal blood pressure is 120 over 80, with the 120 being the systolic pressure (the peak pressure when the heart contracts) and the 80 being the diastolic pressure (the resting pressure when the heart is at rest). They also discuss the importance of not letting blood pressure get too high, as it can lead to serious health issues like kidney failure, stroke, and heart attack. The paragraph emphasizes the need for lifestyle modifications before resorting to medication and the significance of both systolic and diastolic pressures in maintaining overall health.
👩⚕️ Home Blood Pressure Monitoring and White Coat Hypertension
This paragraph addresses the concept of home blood pressure monitoring and the phenomenon known as white coat hypertension. The doctors express their support for patients to measure their blood pressure at home, as it can help identify whether high readings in a clinical setting are consistent with home readings. They mention that approximately 25 to 30 percent of patients experience elevated blood pressure in the doctor's office, which may not be the case when measured at home. The paragraph also humorously touches on the topic of wearing a white coat and its association with medical professionals, suggesting that wearing one on TV might be an upcoming event for the doctors.

Highlights
A normal blood pressure is 120 over 80, which is considered optimal.
The 120 represents the peak blood pressure when the heart squeezes blood out.
The 80 is the resting pressure, which is the residual pressure that keeps blood moving through the organs.
Systolic pressure (120) is the maximum pressure during a heartbeat, while diastolic (80) is the pressure when the heart is at rest.
Blood pressure is measured in millimeters of mercury (mmHg).
When blood pressure is between 130 and 140, it's a cause for concern.
A blood pressure reading above 140 over 90 in Canada may warrant medication.
Lifestyle modifications are recommended before considering medication for high blood pressure.
High blood pressure can damage organs such as the brain and kidneys, leading to stroke or kidney failure.
High blood pressure increases the risk of heart attack by putting excessive pressure on coronary arteries.
Both systolic and diastolic pressures are important and neither is considered more important than the other.
Home blood pressure monitoring is encouraged as it can help identify white-coat hypertension.
White-coat hypertension is when blood pressure is elevated in a clinical setting but normal at home.
Doctors recommend patients take their blood pressure at home to get a more accurate reading.
Patients should be in charge of their own health and blood pressure management.
The show 'Talking with Docs' aims to educate viewers on health topics with expert doctors.
Dr. Heffernan, a cardiologist, explains the importance of understanding blood pressure readings.
