Cardiovascular disorder Flashcards
Artherosclerosis
Is a disease in which the inside of an artery narrows due to the build up of plaque.
Traditional view of Artherosclerosis
- Lipid accumulation and calcification
- Artery wall damages (smoking, high blood pressure, stress, LDL)
- Lipids and salta accumulates on the damages artery wall –> plaque is formed
Modern view of artherosclerosis
inflammatory processes are present in each stage -> the important of immune system
Hypertension
Pressure on the artery walls during contraction and relaxation of the heart
Types of hypertension
- Essential
- Secondary (consequence of renal disease or hormonal problems)
- “white coat”
- During pregnancy
Blood pressure values (normal)
SBP < 120
DBP < 80
Blood pressure values (high)
SBP <140
DBP > 90
Hypertension; main problem
Non-adherence, about 50% of patient do not take their medicine as prescribed
- Lack of treatment is the main cause of the CV-consequences of hypertension
Hypertension; psychological focus
- enhancing complience
- exercies
- lowers blood pressure 3-5 a week, 30 minutes is enough (more is not better)
- exercise may serve as the only therapy requires in some mild hypertensive subjects
Types of cerebrovascular disease (stroke)
- Ischaemic stroke: the blood vessels is blocked, and not sufficient blood supply
- Haemorrhagic stroke: bleeding
- Transient ischemic attach: symptoms resolved within 24 h.
Symptoms of stroke
FAST (Facial weakness, Arm weakness, Speech problems, Time to call 999)
- Unilateral symptoms in most cases
- Hemiplegia
- Inability to produce speech
- Altered vision
- Altered movement coordination
- Loss of consciousness
Consequences of stroke
- The main cause of long-term disability
- Depend on the brain area affected and the size of the damage
- Also depend on time between the onset of symptoms and the treatment
Types of heart diseases
Ischaemic heart disease:
- Angina pectoris
- Myocardial infarction
Acute coronary syndrome
- Unstable angina
- Myocardial infarction
Arrtyhmia
Heart failure
Sudden cardiac death
Symptom and diagnostic criteria of heart disease
Chest pain radiating into the shoulders, arms, neck or lower jaws
May be atypical (especially in woman)
Criteria of myocardial infarction
Two out of the following:
- chest pain
- elecated enzyme levels
- changes in ECG
Risk factors for CVD
Modifiable and non-modifiable
Behavioral risk factors account for 80% of coronary disease and stroke
Risk factors tend to co-occur, especially in people with low SES
Non-modifiable risk factors of CVD
age
sex
genetics (family history of CVD, ethnicity)
Modifiable risk factors of CVD
smoking high cholesterol level high blood pressure diabetes sedentary life style overweight, obesity stress (psychosocial risk factor) alcohol consumption
Psychosocial risk factors of CVD
hostility anger type a behavior pattern depression and related concepts (hopelessness, fatigue, exhaustion) anxiety low social support
Coronary heart disease (psychosocial factors)
Two major topics
- hostility, anger, type A behavior pattern
- Negative emotionality: depression, anxiety and related notions (vital exhaustion, hopelessness, fatigue)
Type A behavior pattern (TABP)
Rosenman and Friedman = at the end of 1950 (cardiologists)
“combination of certain personality traits such as excessive competitive drive, persistent desire for recognition, advancement and achievement, and peristent inclination on one hand and of chronic immersion in “deadlines” on the other hand”
Charcateristics:
- time urgency, impatience
- free-floating hostility
- competiviteness
Measuring type A behavior
Self-assessment:
Time urgency:
- symptoms: hurrying while walking, eating, extreme punctuality, intense aversion to having to wait in a due
- psychomotor signs: chronic facial tension, tense posture, quick speech, excessive facial sweat
Fluctuating hostility:
- Symptoms: frequently getting angry while driving, grinding of teeth, irritability easily provoked, discomfort when having to face pretty mistake
- psychomotor signs: facial hostility, tightening the hand during a conversation, hostile laughter
ARIC study on anger and CVD
high trait anger -> significant higher rate of cardiac death
Framinghan heart study and CVD
suppressed hostility is an independent risk factor of CHD in both sexes
