- Risks of Hypertension Eleni Rapsomaniki and her colleagues analyzed medical records of 1.25 million people in the United Kingdom to see how hypertension affects the risk of cardiovascular disorders. They looked at records of people who at 30 years old had no history of heart disease or stroke, although some had high blood pressure. By looking at which of these people later had a heart attack or stroke, the researchers were able to estimate the lifetime risks of these disorders in people with, and without high blood pressure. FIGURE 36.19 shows the researchers estimates of the lifetime risk for heart attack and for transient ischemic attack (TIA), a type of stroke. FIGURE 36.19 Lifetime risks of heart attack and TIA (a type of stroke), with and without hypertension at age 30. A transient ischaemic attack (TIA), sometimes called a mini-stroke, is caused by a temporary blockage of a blood vessel that supplies blood to the brain. Which is a person who has hypertension at age 30 more likely to have by age 60, a heart attack or a TIA?Listen to this CDC podcast (http://openstaxcollege.org/l/CDCpodcast) to learn about hypertension, often described as a silent killer. What steps can you take to reduce your risk of a heart attack or stroke?Madre-Cacao, a 69-year-old patient with arteriosclerotic heart disease and diabetes mellitus develops congestive heart failure (CHF). Brought to the emergency room (ER) by a neighbor, she goes into cardiac arrest. There is no family member to give consent for cardiopulmonary resuscitation (CPR). Should Dr. Catoc, the ER physician perform CPR without consent? Discuss.
- Why it's difficult to produce adequate blood flow through the tissues?25 year old male motorcyclist was brought into the emergency department following an accident. The patient vital signs were blood pressure 82/40 , heart rate 130, minimal urinary output. Why did his blood pressure dropped , pulse increased and how his body systems will respond to bring the blood pressure back to normal .T/F question Arteries carry blood away from the heart. The smallest blood vessels are called arterioles. The SA node pacemaker is located in the left atrium wall. Systolic blood pressure is the highest blood pressure reading. Atherosclerosis occurs when plaque forms on the inner walls of arteries.
