Middle-age patients who experience moderate to severe angina (grading by classes II, III, and IV) have a five-year survival rate of approximately 92%. Classification
Stable angina
Also known as effort angina, this refers to the classic type of angina related to myocardial ischemia. A typical presentation of stable angina is that of chest discomfort and associated symptoms precipitated by some activity (running, walking, etc.) with minimal or non-existent symptoms at rest or after administration of sublingual nitroglycerin. Symptoms typically abate several minutes after activity and recur when activity resumes. In this way, stable angina may be thought of as being similar to intermittent claudication symptoms. Other recognized precipitants of stable angina include cold weather, heavy meals, and emotional stress. Unstable angina
Unstable angina (UA) (also "crescendo angina"; this is a form of acute coronary syndrome) is defined as angina pectoris that changes or worsens.It has at least one of these three features:

it occurs at rest (or with minimal exertion), usually lasting more than 10 minutes
it is severe and of new-onset (i.e., within the prior 4–6 weeks)
it occurs with a crescendo pattern (i.e., distinctly more severe, prolonged, or frequent than before).UA may occur unpredictably at rest, which may be a serious indicator of an impending heart attack. What differentiates stable angina from unstable angina (other than symptoms) is the pathophysiology of the atherosclerosis. The pathophysiology of unstable angina is the reduction of coronary flow due to transient platelet aggregation on apparently normal endothelium, coronary artery spasms, or coronary thrombosis.
Lower urinary tract symptoms (LUTS) refer to a group of clinical symptoms involving the bladder, urinary sphincter, urethra and, in men, the prostate. The term is more commonly applied to men—over 40% of older men are afected—but lower urinary tract symptoms also affect women. The condition is also termed prostatism in men, but LUTS is preferred. Symptoms and signs
Symptoms can be categorised into:

Filling (storage) or irritative symptoms
Increased frequency of urination
Increased urgency of urination
Urge incontinence
Excessive passage of urine at night

Voiding or obstructive symptoms
Poor stream (unimproved by straining)
Hesitancy (worsened if bladder is very full)
Terminal dribbling
Incomplete voiding
Urinary retention
Overflow incontinence (occurs in chronic retention)
Episodes of near retentionAs the symptoms are common and non-specific, LUTS is not necessarily a reason to suspect prostate cancer. Large studies of patients have also failed to show any correlation between lower urinary tract symptoms and a specific diagnosis. Also, recently a report of lower urinary tract symptoms even with malignant features in the prostate failed to be associated with prostate cancer after further laboratory investigation of the biopsy. Causes
Benign prostatic hyperplasia (BPH)
Bladder stone
Cancer of the bladder and prostate
Detrusor muscle weakness and/or instability
Diabetes
Use of ketamine
Neurological conditions; for example multiple sclerosis, spinal cord injury, cauda equina syndrome
Prostatitis, including IgG4-related prostatitis
Urethral stricture
Urinary tract infections (UTIs)

Diagnosis
The International Prostate Symptom Score (IPSS) can be used to gauge the symptoms, along with physician examination. Other primary and secondary tests are often carried out, such as a PSA (Prostate-specific antigen) test, urinalysis, ultrasound, urinary flow studies, imaging, temporary prostatic stent placement, prostate biopsy and/or cystoscopy.
