CARDIAC
CONDITIONS
Hypertension
15% of the general population can be regarded as hypertensives.
Hypertension is defined arbitrarily at levels above generally accepted normals.
Classification Systolic BP9(mmHg) Diastolic BP(mmHg)
Normal <120 AND <80
Pre-hypertension 120-139 OR 80-89
Stage 1 hypertension 140-159 OR 90-99
Stage 2 hypertension ≥160 OR ≥100
White coat hypertension
A transient increase in blood pressure in normal individuals when blood pressure is recorded in a hospital or in a physician's clinic.
Consider either carefully obtained home values using an appropriately calibrated BP monitor or obtaining 24-hours ambulatory BP measurements.
Isolated ambulatory or masked hypertension
It is reverse phenomenon of "white coat hypertension" in which individuals with normal office blood pressure (<140/90mmHg) may have elevated ambulatory or home blood pressure values.
Such individuals have been slown to have greater than normal prevalence of organ damage, with an increased prevalence of metabolic risk factors compared with subjects with a truly normal blood pressure.
Paradoxical hypertension
Patients on antihypertensive agents, paradoxically show increase in blood pressure.
Paitents with diabetes and hypertension on β-blockers develop paradoxical rise in blood pressure if they develop hypoglycaemia. This occurs due to sympathetic stimulation following hypoglycaemia.
Patients with bilateral renal artey stenosis who are given ACE inhibitors.
Administration of pure β-blockets to patients with phaeochromocytoma.
Classification
Primary or essential hypertension
Accounts for 85% of the cases
Not possible to define specific underlying cause
70% of them have a positive family history
Secondary hypertension
Accounts for 15% of the cases
Consequence of specific disease or abnormality
Causes
Coarctation of aorta
Renal causes - Glomerulonephritis, chronic pyelonephritis, collagen vascular diseases, polycystic kidney disease, renal artery stenosis
Endocrine causes - Phaeochromocytoma, Cushing's syndrome, Conn's syndrome, hyperparathyroidism, acromegaly, primary hypothyroidism, hyperthyroidism, congenital adrenal hyperplasia
Alcohol and drugs - Oral contraceptives, anabolic steroids, corticosteroids, NSAIDs, COX-2 inhibitors, carbenoxolone, sympathomimetics, cyclosporin, sibutramine, bromocriptine, erythropoietin
Pre-eclamptic toxaemia
Miscellaneous - Obstructive sleep apnoea
Common causes of isolated systolic hypertension are:
Atherosclerosis
Aortic regurgitation
Patent ductus arteriosus
Thyrotoxicosis
Coarctation of aorta
Symptoms
Clinical features due to hypertension per se
Majority are asymptomatic and hypertension is detected on routine examination.
Acute hypertension causes transient headache and polyuria.
Long-standing hypertension leads to left ventricular hypertrophy and heaving apical impulse.
Left atrial hypertrophy and fourth heart sound.
Aortic component (A2) of second heart sound is accentuated.
Very short early diastolic murmur.
Fundal changes.
Clinical features due to causes of hypertension
History of intake of alcohol or drugs like oral contraceptives, corticosteroids, NSAID's , carbenoxolone or sympathomimetic agents.
Radiofemoral delay, upper limb hypertension, collaterals aroudn scapulae and systolic murmur over spine suggest coarctation of aorta.
Panic attacks, paroxysmal headache and palpitations suggest phaeochromocytoma, Skin stigmata of neurofibromatosis may also suggest phaeochromocytoma.
Recurrent back pain, undiagnosed fever and recurrent urinary infections suggest chronic phlyeonephritis.
Enlarged palpable kidneys in polycystic kidney disease.
Bruit over the abdomen in the lumbar region suggests renal artery stenosis.
Characteristic facies and habitus in Cushing's syndrome.
Treatments
Hypertension is a lifestyle disorder. It might require long term treatment depending on patient. Homeopathy works very successfully on heart and its arteries and by doing this it helps in reducing and managing hypertension in acute and chronic cases both.
Few homeopathic medicines which help in hypertension are sulphur, nux vomica, kali carbonica etc .
Strict diet control which includes less oily and salty food and exercise is mandatory for long time to maintain this disease.
