Sameer A. Sayeed, MD, Cardiology (Cardiovascular Disease), answeredHigh blood pressure is dangerous. It can lead to damage to the coronary arteries, leading to coronary artery disease, heart attacks and heart failure. It can also lead to cerebrovascular disease and strokes. High blood pressure can also affect peripheral arteries, leading to inadequate blood flow to the legs, causing gangrene; inadequate blood flow to the kidneys, leading to kidney failure; and rupture of the aorta and other major vessels, leading to death.
Emilia Klapp, Nutrition & Dietetics, answeredHigh blood pressure, also called hypertension, can be life-threatening because it causes two conditions that make the heart work harder:
- It causes the artery walls to thicken, which reduces blood flow.
- It makes the inside of the arteries rough, which contributes to the formation of mounds of fat and debris called plaque and also reduces the space available for blood to circulate.
Healthy arteries are vitally important. They need to remain strong and elastic. Their inner lining should be smooth for the blood flow that enriches the organs and tissues with adequate nutrients and oxygen.
Blood pressure is the force of blood against the walls of arteries. Blood pressure can rise and fall during the day or during certain activities. When blood pressure stays elevated over time, it is called high blood pressure or hypertension.
High blood pressure can damage the cells of your arteries' inner lining. Other conditions can aggravate the damage from hypertension, making the artery walls thick and stiff. Fats from your diet enter your bloodstream, pass through the damaged cells and collect to start atherosclerosis, or hardening of the arteries.
In severe, untreated cases, these changes can affect arteries throughout your body, blocking blood flow to your heart, kidneys, brain, arms and legs.
The damage can cause many problems, including chest pain (angina), heart attack, heart failure, kidney failure, stroke, blocked arteries in your legs or arms (peripheral arterial disease), eye damage, and aneurysms.

If you have high blood pressure, or hypertension, you may not experience any symptoms. That does not mean that high blood pressure is not dangerous. If your blood pressure reading is consistently above 120/80 mmHg, you should work with your doctor to lower it through medication, diet, exercise and stress reduction. When you have high blood pressure, your heart is working extra hard. This can cause the heart muscle to grow very thick. Over time, the heart cannot continue to work so hard and it will begin to fail, or weaken.
High blood pressure is when blood pushes against your artery walls with too much force. Arteries are the blood vessels that carry oxygen-rich blood away from your heart to the rest of your body. Hypertension can damage the walls of the arteries and contribute to cardiovascular diseases that lead to heart attack, stroke and kidney failure. The damage to your cardiovascular system takes places silently over years and decades, so it is important to monitor your blood pressure and seek early treatment if you have high blood pressure.Helpful? 1 person found this helpful.
Nassir Azimi, MD, Interventional Cardiology, answeredIn brief, yes. High blood pressure above 200 systolic and 100 diastolic can lead to acute complications such as stroke, heart failure or kidney damage. Long-term pressures above 140/85 can cause problems with the heart, the brain, the kidneys or blood vessels.
Honor Society of Nursing (STTI) answeredIf your blood pressure stays high, over time your risk of heart attack and other problems caused by atherosclerosis are greatly increased. High blood pressure can cause your heart to enlarge and weaken, resulting in heart failure. With heart failure, your heart can no longer pump adequate blood throughout your body.
Hypertension can also increase the chance of abnormal bulges or balloons in the artery walls called aneurysms. Arteries are blood vessels that carry the blood from your heart to different parts of your body. Aneurysms commonly appear in the main artery, the one that carries the blood from the heart to the body. Also, these abnormal bulges can occur in the arteries of the brain, legs, intestines and spleen. Aneurysms can burst and result in death.
Scripps Health answeredHigh blood pressure (or hypertension) affects one in three adults in the United States. It increases their risk of heart attack, heart failure, kidney failure and stroke.
