  2. Angina - Wikipedia

    en.wikipedia.org/wiki/Angina

    The primary factor differentiating unstable angina from stable angina (other than symptoms) is the underlying pathophysiology of the atherosclerosis. The pathophysiology of unstable angina is the reduction of coronary blood flow due to transient platelet aggregation on apparently normal endothelium , coronary artery spasms, or coronary thrombosis .

  3. Coronary artery disease - Wikipedia

    en.wikipedia.org/wiki/Coronary_artery_disease

    The first investigation when CAD is suspected is an electrocardiogram (ECG/EKG), both for stable angina and acute coronary syndrome. An X-ray of the chest, blood tests and resting echocardiography may be performed. [71] [72] For stable symptomatic patients, several non-invasive tests can diagnose CAD depending on pre-assessment of the risk profile.

  4. Canadian Cardiovascular Society grading of angina pectoris

    en.wikipedia.org/wiki/Canadian_Cardiovascular...

    The CCS grading system for angina is, in part, used to evaluate fitness to fly by the British Cardiovascular Society.They recommend no action by class I and II patients with stable angina, class III should consider mobility assistance from airport staff and in-flight supplemental oxygen therapy, and that class IV patients should ideally defer their travel plans or travel with a medical ...

  5. Coronary ischemia - Wikipedia

    en.wikipedia.org/wiki/Coronary_ischemia

    Angina may start to occur when the vessel is 70% occluded. [9] Lack of oxygen may also result in a myocardial infarction (heart attack). [26] CAD can be contracted over time. Risk factors include a family history of CAD, smoking, high blood pressure, diabetes, obesity, inactive lifestyle, mental stress and high cholesterol.

  6. Arterial occlusion - Wikipedia

    en.wikipedia.org/wiki/Arterial_occlusion

    Under physical exertion, CAD induces chest pain, termed 'stable angina'. Stable angina may deteriorate into unstable angina, marking the initiation of Acute Coronary Syndrome, which may further deteriorate into a myocardial infarction. Risk factors for CAD include smoking, [26] high cholesterol, obesity, and family history of CAD. Primarily ...

    Three risk factors — high blood pressure, smoking and atrial fibrillation (which is an irregular heart rhythm) were linked with higher risk of severe compared to mild-moderate stroke,” said Dr ...

  8. Acute coronary syndrome - Wikipedia

    en.wikipedia.org/wiki/Acute_coronary_syndrome

    In contrast with stable angina, unstable angina occurs suddenly, often at rest or with minimal exertion, or at lesser degrees of exertion than the individual's previous angina ("crescendo angina"). New-onset angina is also considered unstable angina, since it suggests a new problem in a coronary artery. [8]

  9. Variant angina - Wikipedia

    en.wikipedia.org/wiki/Variant_angina

    Variant angina differs from stable angina in that it commonly occurs in individuals who are at rest or even asleep, whereas stable angina is generally triggered by exertion or intense exercise. Variant angina is caused by vasospasm, a narrowing of the coronary arteries due to contraction of the heart's smooth muscle tissue in the vessel walls. [3]
