Chapter 10 Flashcards
(102 cards)
Is dying of heart break scientifically possible? If so, what is it called and how does it work?
> It is referred to as “broken-heart syndrome” (or takotsubo syndrome in Japan)
> it is a stress-induced cardiomyopathy (disease of the heart muscle)
> When an individual endures a significant amount of emotional distress, the body is flooded with hormones that directly impact the heart.
> Rapid and immense levels of these hormones can influence the heart to enlarge and pump blood inefficiently
> these effects are typically transient and most individuals fully recover within two months; however, this intense hormonal cascade can lead to heart failure and in rare cases death
Diseases of the cardiovascular system include those that occur in what organ, what two sytems?
> those that occur within the heart and the blood transport or circulatory system (i.e., veins and arteries).
Is CVD a leading cause of death? If so, for which countries?
> these diseases are among the leading causes of death for North American men and women
Are people living with chronic CVD? (What do the mortality rates say…)
> Fortunately, due to advances in treatment, mortality rates from cardio-vascular disease (CVD) have significantly declined in developed nations such as Canada and the United States
> Since mortality rates have de-clined, and onset of disease has not, this means that many people are living with chronic CVD.
What factors are associated with the onset of CVD and its progression, as well as the quality and quantity of life of those with CVD?
> psychological factors
such as depression or behavioural changes that come with the diagnosis?
The optimal management of heart disease requires what?
> requires multiple behavioural changes, such as abstinence from tobacco, regular physical activity, and adhering to a heart-healthy diet
Coping with a heart condition and its treatment can also contribute stress in interpersonal relationships and role functioning (e.g., paid and unpaid work), thus impacting what?
> impacting quality of life.
The biopsychosocial model provides a framework describing how behavioural and social factors contribute to the onset of CVD- how does it work?
> Specifically, injury to the endo-thelium is often caused by hypertension (high blood pressure), diabetes (problems regulating blood sugar), and hyperlipidemia (too much cholesterol).
> These injuries are associated with modifiable behavioural and social risk factors such as smoking, abdominal obesity, physical inactivity, unhealthy diet, and psychosocial distress
A temporary restriction of blood flow is known as what?
> ischemia (tissue cells remain alive but their functioning is disrupted), in which the heart tissue by the vessel is deprived of oxygen.
In the instance of complete blockage, there is no distribution of oxygen and other nutrients to the tissues supplied by that artery- what is this called when it occurs in the arteries?
> When this occurs in the coronary arteries serving the myocardium (heart muscle), this is known as a “heart attack,” or myocardial infarction (mi).
The continuum from unstable angina (i.e., ischemia causing chest pain that does not remit with rest) to MI is known as what?
> as acute coronary syndrome
What is the end stage of heart disease?
> Heart failure is an end-stage of heart disease, when the heart cannot pump sufficient blood to meet the demands of the body
What is the average life span of heart disease?
> the average lifespan of heart-failure patients is approximately five years following hospital discharge
What are other forms of heart disease?
> there are other heart diseases related to the function of the valves (ensures directional flow)
> the contraction of the heart (disturbances called arrhythmias,
> some of which can cause sudden cardiac death
> the heart muscle (i.e., cardiomyopathies),
> infections,
> structural defects (i.e., congenital heart disease).
What are the warning signs of a heart attack?
> Chest discomfort- uncomfort-able pressure, squeezing, fullness, or pain.
> Discomfort of other areas of the upper body—one or both arms, the back, neck, jaw, or stomach.
> Shortness of breath—with or without chest discomfort.
> Other signs—may include breaking out in a cold sweat, nausea, or light-headedness.
What are the symptoms of heart attack for men?
> “experience classic warning signs”
> Uncomfortable pressure, fullness, squeezing or pain in the centre of the chest that goes away and comes back
> Pain that spreads to the shoulders, neck, or arms
> Chest discomfort with lightheadedness, fainting, sweating, nausea, or shortness of breath
When are the symptoms of heart attack for women?
> Shortness of breath or difficulty breathing
> Nausea, vomiting or dizziness
> Back or jaw pain
> Unexplained anxiety, weakness, or fatigue
> Palpitations, cold sweats, or paleness
> may experience the classic symptoms, but they are often milder
What is the trigger for heart attacks in women?
( What type of stress )
Emotional Stress
What is the trigger for heart attacks in men?
> Men most often report physical exertion prior to heart attacks.
In Canada, how many individuals experience an MI each year? How many of these result in death?
> over 70,000
14,211 result in death
How many in the US experience MI and how many will experience angina?
> In the United States, recent annual estimates suggest that 750,000 adults will have an MI and 3.4 million will experience angina each year
There is an associated financial burden; CVD costs the Canadian and American economies what?
> more than $12.1 billion and $316.6 billion, respectively
What are the disparities in heart disease? (specifically with relation to ethnicity)
> CD tends to occur in men and women of African ancestry at an earlier age than in Caucasians
> death rates are higher in persons of African ancestry across all age categories
> ethnic minority groups have been shown to have relatively more limited awareness regarding CVD risk factors and less access to health care
What do the disparities of CVD highlight in terms of treatment?
> these discrepancies high-light the need for individualized, culturally sensitive methods of CVD prevention, diagnosis, and treatment
