Other antihypertensive

Vasodilators. (Hydralazine, minoxidil, diazoxide, sodium nitroprusside)

Produce dilation of the arterioles by direct action on smooth muscle (relaxed). This dilation causes salt retention tachycardia and so are often used in combination with a diuretic and a beta blocker to counteract these effects.

Hydralazine is used as a third drug in hypertension. Be careful with the dose. If this is greater than 200 mg there is a risk of a syndrome similar to lupus erythematosus. Read the rest of this entry »

Act by blocking many effects of adrenaline in the body, particularly the stimulating effect on the heart. The result is that the heart beat slower and with less force.

Effects of beta-blockers in hypertension

- Reduce the cardiac
- Reduce the stroke volume
- Reduce the heart rate
- Inhibit renin secretion
- Have central antisimpático effect
- Stimulate the production of kinins
- Stimulate the release of atrial natriuretic peptide
- Can produce a feeling of fatigue, decreased exercise capacity, impotence, cause asthma, fatigue and lethargy that limits their use.
- Some of them can reduce levels of “good” cholesterol or HDL.
- They are most suitable in cases of hypertension with tachycardia, ischemic heart disease in migraine associated with glaucoma. Read the rest of this entry »

Changes in lifestyle, including dietary changes and exercise, are by far the most important in BP control, but often need a combination of therapies, including drugs. Regardless of the cause of hypertension, there is a wide range of drugs to treat, usually used in stages to find the drug plan that works staff in every hypertensive patient.

DIURETICS

Generally, the first drug of choice in hypertension is a diuretic. Increased urine output and exit the body, which serves to lower the TA, both lost fluids because it decreases as the resistance to blood flow in the vessels of the body. (However, thiazides may increase blood cholesterol levels). Read the rest of this entry »

EXERCISE

A program of aerobic exercise helps strengthen the heart, to lose weight and control blood pressure. No one knows the exact mechanism by which helps lower blood pressure. There must be a proper exercise to every age and every person, thus making half-hour jog 2 or 3 days a week is enough for most people.

ESTABLISHMENT OF THE INDIVIDUAL THERAPY

Since hypertension does not usually cause symptoms, how to know if the drugs are working is to take the tension, always start at the same time (blood pressure varies throughout the day). Once pressure has normalized arterials should take one or two times a week, but at different times. The goal of treatment is to keep blood pressure in normal ranges throughout the day.

In most cases, the cause of hypertension is unknown. However, it can be treated effectively, reducing the TA to manageable levels or normal and avoiding all the serious consequences of hypertension, which would continue a normal life expectancy.

Treatment of hypertension based on the following points:

- Diet
- Exercise
- Treatment with drugs.

DIET

Salt restriction and weight reduction: Read the rest of this entry »

Is stress always leads to hypertension?

From the epidemiological point of view known to the people who have survived natural disasters or war show elevated levels of blood pressure that last weeks or months and then return them to normal.

Can not be said to date, and in general, that the hyperreactivity to stress in specific situations to predict the future development of hypertension. Individual differences are important, including those arising from operation exaggerated sympathetic nervous system and the presence or absence of family history of hypertension.

What is the impact of stress in hypertension?

Work activity is associated with increases in mean arterial pressure may or may not cross the threshold of hypertension. Read the rest of this entry »

What is stress?

It is a requirement that the environment imposes on a body. The individual is faced with a threatening situation and aggressively to which is to use adaptive resources in order to avoid a deterioration of their physical and / or mental.

The same situation can be assessed as threatening or not by different individuals, so their ability stressful is different for each.

The stress reaction is very complex and constitute a succession of events such neuronal, muscular, cardiovascular, immune and hormonal systems. Laboratory experiments show that the cardiovascular system is very sensitive to external stimuli threatening. Read the rest of this entry »

How I can control blood pressure?

The NHLBI has found that five lifestyle changes can help control blood pressure:

- Keep your weight as close to normal. Eating fruits, vegetables, grains, and nonfat dairy products.

- Limit your daily sodium (salt) to 2000 milligrams or less if you have high blood pressure. Read the information found in food labels that say how much sodium is in one serving. Keeping a daily salt intake.

- Get plenty of exercise, which means at least 30 minutes of moderate activity such as walking, most days of the week. Read the rest of this entry »

The kidneys are very important for healthy blood pressure and, in turn, blood pressure can also affect the health of the kidneys. High blood pressure, also called hypertension, can damage the kidneys.

What is hypertension?

Blood pressure measures the force of blood against the walls of blood vessels. Blood pressure that remains high for a long time is called hypertension. If too much fluid in the body increases the amount of fluid in blood vessels and raises blood pressure. The Narrow or clogged blood vessels also raise blood pressure.

If you have high blood pressure, consult your doctor regularly.

What harm does high blood pressure to the kidneys?

High blood pressure makes your heart work harder and, over time, can damage blood vessels throughout the body. If damaged blood vessels in the kidneys, these organs may fail to remove impurities and extra fluid from the body. The extra fluid in blood vessels may then raise blood pressure even more. It’s a dangerous cycle. Read the rest of this entry »

DEFINITION

The excess pressure in the arteries maintained for a period of years and untreated can lead to many complications. It describes the most important.

ARTERIOSCLEROSIS

When blood vessels are subject to increased pressure maintained, respond to thicken, making them less flexible. In these arteries stiff easily fixed with excess fats that circulate in the blood. At the level of kidney arteries, arteriosclerosis causes less flow reaches the kidneys, and kidneys respond by releasing renin, a hormone that in turn causes an increase in the TA. This exaggerates hypertension and causes more damage to blood vessels. Read the rest of this entry »
