Cardiovascular is something relating to the heart hence the term cardiovascular disease when referring to an illness that hinders proper heart function. Cardiovascular disease is a collective term for different problems of the heart or blood vessel to prevent proper pumping and flow of blood to all body parts. Below are some examples of cardiovascular diseases:
- Heart failure
- High blood pressure (hypertension)
- Cerebral vascular disease (stroke)
- Coronary heart disease (heart attack)
- Congenital heart disease
- Rheumatic heart disease
Delirium is a transient and acute but reversible fluctuation disturbance in the level of cognition, attention and consciousness. Other names for delirium are toxic or metabolic encephalopathy or confusional state.
The cause can be any disorder or drug intolerance.
The diagnosis for delirium is clinical with the use of imaging and laboratory tests to identify the cause. Correcting the cause and other supportive measures are the approach to treating delirium.
Delirium can occur at any stage of life but mostly affects the elderly. Approximately 10% of the elderly patients in the hospital have hallucination and 15-50% experiences the condition at a particular time in their hospitalization. Delirium is also frequent after surgery, among ICU patients and nursing home residents.
It might also affect the younger people usually because of life-threatening systematic disorder or drug use.
Symptoms and Signs of Delirium
These are the primary signs that characterize the presence of fever: The level of consciousness fluctuates making the patients become disoriented to time, place and sometimes person. The patient might have hallucinations, paranoia and delusions. It is common for the patient to have confusion regarding their daily events and daily routines as well as changes in personality. Delirium might disorganize thinking and speech with exceptional rapidity, slurring, aphasic errors, neologisms or chaotic patterns. Symptoms of delirium keep fluctuating over minutes or hours. They might lessen as the day progresses but become worse at night.
Difficulties in maintaining, focusing or shifting attention

A diagnostic test or procedure is an examination that identifies specific areas of strength and weakness to determine the condition, illness or disease in a person. For instance, physicians may use MRI (Magnetic Resonance Imaging), Electromyography (EMG) or Computer Assisted Tomography (CAT scan to determine if there is impingement of a nerve root by a herniated disc.
The ability and range of diagnostic test continuously evolve as researchers find a way to detect diseases earlier, get more detail and get an accurate diagnosis in many people across all regions of the globe. There are many attempts to find new ways of performing diagnostic tests, but these are the latest developments in the diagnostic technologies.
Cancer has become such a killer, but researchers have invented another way of testing and detecting eight most frequent types at once. These include the elusive pancreatic and liver cancers that are difficult to detect. As the new technology develops, doctors will one time use it to spot cancers in the early stages even before the onset of symptoms to improve chances of treatment and survival. Cancer SEEK looks for various compounds that could be early signs of cancer from the blood. The compounds it checks include 16 different cancer driver genes with association to tumors and eight proteins.
The intention is to make cancer screening a routine activity so that patients who visit a health facility for an annual physical checkup can get also get a blood screening for cancer at the same time. An additional benefit is that cancer SCREEN appears to have ability for screening for these five cancers for which other screening tests fail to detect.
Blood pressure cuff is a medical device that comprises of a rubber piece or a similar material that a clinician wraps around the arm of a patient and inflates it to measure the blood pressure.
The purpose of blood pressure cuff is to take blood pressure. The cuff has an inflatable bladder made of rubber for fastening around an arm. A pressure meter indicates the pressure off the cuff. A clinician uses a small handheld air pump to inflate the blood pressure cuff.
