Why Do I Get Thrust Every Month

coronary heart disease

ì Synonyms: CHD = coronary artery disease ischemic coronary artery disease

ì Definition: manifestation of atherosclerosis in the coronary arteries.

ì process:



  1. Atherosclerosis in the coronary arteries


  2. development of stenosis


  3. reduced blood flow to the heart muscle


  4. mismatch between 0 2 -demand and O 2 offer

ì Etiology: [ á increased =]










risk factors of first order


2 risk factors = heart attack risk increased 4-fold


3 risk factors = risk of heart attack 10-fold increase

risk factors of second order


  • hypertension

  • smoking

  • diabetes mellitus

  • dyslipidemia

  • genetic predisposition

  • age

  • male gender

  • metabolic syndrome


  • sedentary

  • stress

  • lipoprotein A á

  • fibrinogen á

  • homocysteine á

ì pathophysiology (4 degrees of severity of coronary stenosis)

Grade 1 25 - 49%

; Grade 2 50 - 74% Grade 3 75

- 99% (critical stenosis)

, Grade 4 100% (total occlusion)

Ü only 75% the first symptoms

two forms of CHD


latent coronary heart disease ~ KHK manifest

(asymptomatic (Symptomatische DL)

DL; Stumme ;

Ischämie)

                                                 

diseases manifest CHD



























diseases share of onset (in%) Description
angina pectoris

chest pain due to reversible Myocardischmie
heart attack

25

Ischemic Myocardnekrose
heart failure

Ischemic heart muscle damage

arrhythmias

ventricular arrhythmias and ventricular fibrillation
Sudden cardiac death

ì coronary vessels (coronary arteries)


Extras:

# are end arteries

#, there are no anastomoses with the einzellne arteries

# dies at closing tissue from

effect of the risk factor nicotine

adrenal medulla:



  • release of adrenaline and noradrenaline


  • ð peripheral increase in heart rate


  • ð increase in O 2 -consumption of the heart

coronary vessels & Vessels:



  • narrowing of these vessels


  • ð increased vascular resistance


  • ð reduced O 2 offer

vessel walls:



  • promote platelet aggregation


  • increase in fibrinogen levels


  • damage the intima of the arteries


  • ð increase the clotting ability Blood


  • ð encouraging early deposits


  • ð promote atherosclerosis

effect of the risk factor of alcohol









positive negative reduced


  • increase in HDL-cholesterol

  • platelet aggregation

  • reduction of fibrinogen in serum

  • blood pressure reduction with low regular alcohol consumption


  • increase in triglycerides in serum

  • blood pressure with increased regular alcohol consumption (from 30 g / d = 0.3 liters of wine or 0.8 liters of beer)

main complaints / symptoms in diseases of the heart











































symptom statement differential diagnosis
chest pain linksthorakal or retrosternal angina pectoris, pulmonary embolism, heart attack, tuberculosis
dyspnea breathlessness pneumonia, lung CA, heart attack, Tbc
palpitations unpleasant perception of one's own heartbeat heart attack, hyperthyroidism
cyanosis bluish discoloration of lips, mucous membranes, skin hypothermia, pulmonary embolism
distended neck veins by damming the blood before the right heart bronchial CA, pericarditis, valve stenosis
nocturia increased urination at night right heart failure, urinary incontinence
cough

-

flu, colds, pneumonia
syncope sudden, brief loss of consciousness, by reducing supply to the brain with O 2 cardiac arrhythmias, arteriosclerosis
reduced exercise capacity
