Blood Pressure Pills: Stroke Risk And Prevention

High blood pressure, or hypertension, is a major risk factor for strokes. It is the biggest single risk factor, playing a part in about half of all strokes. While high blood pressure is a serious condition, there are things you can do to reduce your risk of a stroke. Over time, high blood pressure can damage and weaken the blood vessels, making it easier for blood clots to form or for arteries to rupture. This can lead to two types of strokes: ischaemic strokes and haemorrhagic strokes. The former is the most common type of stroke and occurs when a blood clot lodges in an artery that supplies the brain with blood. The latter occurs when high blood pressure damages blood vessels inside the brain, causing bleeding in the brain.

While blood pressure medication can be beneficial, it is also risky to wait for hypertension to develop and then treat it to a controlled level. Research shows that the harder hypertension is to control, the higher the risk of stroke, even if treatment is successful.

High blood pressure weakens and damages blood vessels, making it easier for blood clots to form or arteries to rupture

High blood pressure, or hypertension, is when blood travels through blood vessels with more force than is considered healthy. This increased force can damage blood vessel walls over time, causing them to weaken and develop tiny tears. As these tears form, bad cholesterol flowing through the blood attaches to the tears, building up and making the arteries narrower. This process is called atherosclerosis, and it can block the flow of blood, increasing the risk of serious conditions such as a stroke.

High blood pressure can also cause blood vessels to rupture. When this happens in the brain, it is known as a hemorrhagic stroke. This is less common than an ischemic stroke, which is caused by a blood clot in the brain. However, both types of strokes are made more likely by high blood pressure.

The longer high blood pressure goes undiagnosed or uncontrolled, the more serious the risks become. High blood pressure has no symptoms, so it is important to have it checked regularly. If left untreated, it can lead to dangerous complications and even death.

High blood pressure, or hypertension, is the biggest single risk factor for strokes, playing a part in about half of all strokes. Over time, high blood pressure can damage and weaken the blood vessels, making it easier for blood clots to form or for arteries to rupture. This can lead to two types of strokes: ischaemic strokes and haemorrhagic strokes.

Ischaemic strokes, the most common type, occur when a blood clot lodges in an artery that supplies the brain with blood. High blood pressure damages your blood vessels by making them narrower and stiffer, causing a build-up of fatty material. This process is called atherosclerosis. Clots can form on the areas of fatty material, and if a clot travels to the brain, it causes an ischaemic stroke.

Haemorrhagic strokes occur when high blood pressure damages blood vessels inside the brain, causing bleeding in the brain.

High blood pressure can also lead to small vessel disease, which means having damage to the tiny blood vessels deep inside the brain. This makes a stroke more likely and can affect your thinking ability (cognitive problems).

While high blood pressure is a serious condition, there are things you can do to reduce your risk of a stroke, such as taking part in moderate physical activity, maintaining a healthy weight, reducing salt intake, and eating a diet rich in fruits, vegetables, and low-fat dairy products.

Hypertension medication can increase the risk of stroke by 248%

Untreated high blood pressure, or hypertension, can wreak havoc on the body, leading to heart disease and stroke. While hypertension medication is beneficial, research shows that it can increase the risk of stroke by 248%. This risk is as high as the risk associated with untreated hypertension.

A study published in the journal Stroke found that the more medications required to control hypertension, the higher the risk of stroke. The research, conducted by the University of Alabama at Birmingham, followed 26,785 black and white participants aged 45 and above for 6.3 years. At the end of the follow-up period, more than 820 participants had experienced a stroke.

The study showed that the risk of stroke increased by 33% with each additional hypertension medication. Compared to people with systolic blood pressure below 120 mm Hg without treatment, individuals on three or more hypertension medications had 2.5 times the risk of stroke.

The lead researcher, George Howard, emphasised the importance of preventing hypertension in the first place. He suggested that a combination of policy changes and individual commitment to a healthy lifestyle could curb the problem. Proven approaches to prevent or delay the development of hypertension include moderate physical activity, maintaining a healthy weight, reducing salt intake, and consuming a diet rich in fruits, vegetables, and low-fat dairy products.

While hypertension medication can help manage high blood pressure, it is crucial to prioritise primordial prevention, which focuses on preventing individuals from developing pre-hypertension and hypertension in the first place. This approach can help reduce the substantial risk of stroke associated with hypertension and its treatment.

Successfully treated hypertensives on three or more blood pressure medications had a stroke risk 2.5 times higher than those with systolic blood pressure below 120 mm Hg without treatment

The study found that the harder hypertension is to control, the higher the risk for stroke, even if the treatment is ultimately successful. The risk of stroke went up by 33% with each additional blood pressure medicine required to treat blood pressure to the goal. This means that, compared to people with systolic blood pressure below 120 mm Hg without treatment, hypertensive individuals on three or more blood pressure medications had a stroke risk 2.5 times higher.

The study's lead, George Howard, suggested that the way to curb the problem is to prevent hypertension in the first place. There are several proven approaches to preventing or delaying the development of hypertension, including taking part in moderate physical activity, maintaining a healthy weight, reducing salt intake, and eating a diet rich in fruits, vegetables, and low-fat dairy products, and reduced in saturated and total fat. Howard also suggested that some future efforts to prevent hypertension may need to be made through policy changes, such as targeting reductions in sodium levels.

Lifestyle changes such as moderate physical activity, a healthy diet, and reduced salt intake can help prevent hypertension

Lifestyle changes can play a crucial role in preventing hypertension and reducing the risk of stroke. Here are some detailed ways in which you can make these changes:

Moderate Physical Activity

Engaging in regular physical activity is essential for maintaining a healthy blood pressure level. Aim for at least 150 minutes of moderate-intensity aerobic activity each week. This can include activities such as brisk walking, biking, swimming, or even chores like raking leaves or window cleaning. These activities help to strengthen your heart and lungs, making them more efficient at pumping blood and improving your overall cardiovascular health.

Healthy Diet

Adopting a heart-healthy diet is another crucial lifestyle change. The DASH (Dietary Approaches to Stop Hypertension) diet is often recommended and includes whole grains, fruits, vegetables, low-fat dairy, lean meats, poultry, fish, and nuts. This diet is high in protein and fiber while being low in fat, cholesterol, and sugary drinks. Reducing salt and alcohol intake is also beneficial, as they can raise blood pressure.

Reduced Salt Intake

Salt, or sodium, is prevalent in many packaged and processed foods and can quickly lead to excessive sodium intake. Aim for no more than 1,500 milligrams of sodium per day. Reading labels and being mindful of salt intake can help reduce your overall sodium consumption and lower blood pressure.

Weight Management

Even a small amount of weight loss can positively impact blood pressure. Maintaining a healthy weight and waist circumference are important, as excess weight, especially around the midsection, can affect blood pressure readings. For women, a waist circumference of more than 35 inches is considered high, while for men, it's more than 40 inches.

In addition to these changes, quitting smoking, managing stress, and getting adequate sleep of 7-9 hours per night are also essential components of a healthy lifestyle that can help prevent hypertension and reduce the risk of stroke.
