The risk that someone without hypertension at age 30 will have a heart attack by age 85. Introduction: High blood pressure or hypertension is the high force exerted by the blood against the walls of blood vessels. It can lead to many severe complications like increasing the risk of stroke, atherosclerosis, heart diseases, and death. The normal range of blood pressure is 120/80 mmHg, where the first number represents the systolic pressure and the second number represents the diastolic pressure.

Expert Solution

Explanation of Solution

According to the study based on the effect of hypertension, the medical research implies the fact that an individual without hypertension at the age of 30 will have 4 percent chance to develop a heart attack by the age of 85. There are no symptoms or signs appear during the early stage of life. However, symptoms or signs may appear during the late period of life.

Conclusion

The risk that someone without hypertension at age 30 will develop a heart attack by age 85 is about 4 percent.

Summary Introduction

To find: The comparable risk for someone with hypertension at age 30.

Introduction: High blood pressure or hypertension is a medical condition where the blood pressure in the arteries is persistently elevated. Hypotension is the medical term for low blood pressure. Age, body weight, sex, food habits, alcoholism, drug addiction, and physical inactivity are some of the major causes for this condition to occur.

Expert Solution

Explanation of Solution

The risk of hypertension at age 30 is about 7 percent. The chance for cardiac arrest is very high for the people who had hypertension at the age of 30 itself. The chance for cardiac arrest is very less in people with no hypertension at the age of 30. This indicates the fact that maintaining a healthy diet and regular exercise would help to get rid of hypertension at a young age. As a result, they will not develop heart-related issues in their late period of life.

Conclusion

The risk that an individual without hypertension at age 30 will develop a heart attack by age 85 is only about 4 percent, while for the ones with hypertension at age 30 is about 7 percent.

  • Propose 2 physical ways that a human may develop hypertension(abnormally elevated blood pressure). [One of these mechanisms should stem from the blood vessels, and the other at the level of the nervous system]. What are the long-term consequences of elevated hypertension?
    The Effects of Lifestyle, Sex & Genetics on Blood Pressure Many things might affect heart rate, including the physical fitness of the individual, the presence of drugs such as caffeine or nicotine in the blood, and the age of the person. Heart rate and blood pressure work together to ensure that blood reaches cells at a rate that is sufficient to supply nutrients and remove waste products.  If one variable decreases the other will increase to maintain this balance.  For example, if the body detects a drop in blood pressure, it will help to correct this imbalance by increasing heart rate until the body can adjust blood pressure by other methods.  Watch these videos to learn the terminology and science of blood pressure along with how to take a proper blood pressure reading. https://www.ausmed.com/cpd/articles/how-to-take-blood-pressure When a person is well hydrated and healthy the body can make these adjustments without you ever being aware.  But, if a person is dehydrated, taking…
