ANSWER
First question: objectives of different anti-hypertensive treatments and drug therapy for hypertension
Drug Therapy Goals for Hypertension
Reducing blood pressure to target values will help to lower the risk of cardiovascular events like stroke, myocardial infarction, and heart failure.
Aim generally for 130/80 mmHg for most adults.
Protect end organs including kidneys and the heart from harm.
Reduce treatment side effects while raising standard of living.
Antihypertensive Treatments
Diurestics:
Hydrochlorothiazide, furosemide are two examples.
Promoting salt and water excretion will help to lower blood volume.
Often used as first-line treatment.
Angiotensin-converting enzyme inhibitors, or ACE inhibitors:
For instance: Lisinopral, enalapral.
Mechanism: Block the angiotensin I conversion to angiotensin II, hence lowering vasoconstriction.
Indicated for patients having diabetes, chronic renal disease, or heart failure.
Angiotensin II Receptor Blockers: ARBS
For instance, Losartan and Valsartan.
Mechanism: Reverse the actions of angiotensin II to cause vasodilation.
Other choice for those unable of ACE inhibitors.
Blockers of calcium channels (CCBs):
Amlodipine, diltiazem are two examples.
Mechanism: Stop calcium input into vasodilated vascular smooth muscle.
Usually chosen by African Americans.
Alpha-blockers:
For instance: metoprolol, atenolol.
Mechanism: Lower blood pressure by slowing down heart rate and cardiac output.
Indicated for patients suffering with post-myocardial infaredness or heart failure.
Second question: kinds of arrhythmias and their management
Arhythmias: Types
Atrial fibrillation, or AF:
Definition: Chaotic atrial activity causes often irregular and fast heart rhythm.
Treating:
Rate control: Calcium channel blockers or beta-blockers.
Cardioversion or antiarrhythmic medications (amiodarone) control rhythm.
Warfarin, or DOACs, help to lower stroke risk.
Tachycardia (VT): Ventricular
Definition: Maybe fatal fast heart rate starting in the ventricles.
Treating:
Acute: Ladocaine or intravenous amiodarone.
For repeated VT, implantable cardioverter-defibrillator (ICD).
Bradyarrhythmia:
Definition: Sinoatrial node malfunction causes typically sluggish heart rate.
Treatment: installation of a pacemaker.
SVT, or supersaventricular tachycardia:
Definition: fast heart rate starting higher than the ventricles.
Approach: Therapy
Acute: vagal or adenosine movements.
Constant: ablation of a catheter.
Question 3: Atrial Fibrillation
Term: Definition
Disorganised electrical signals in the atria generate the irregular, generally fast heart beat known as atrial fibrillation (AF).
Motives:
In hypertension,
Disease of the coronary arteries.
Disease of the valves in the heart.
Hyperthyroidism.
Signs:
dyspnea.
Tardiness.
dyspnea—shortness of breath.
Inaccuracy.
Complications include:
More chance of stroke brought on by atria’ forming clots.
Heart failure brought on by lowered cardiac output.
Treating:
Regulation of Rate:
Medications included calcium channel blockers (diltiazem) and beta-blockers (metoprolol).
Keep ventricular rate less than 100 beats per minute.
Rhythm Control:
Medicines: sotalol or amiodarone.
Should it be needed, electrical cardioversion.
Anticoagulant:
Medications: Like apixaban, warfarin or direct oral anticoagulants (DOACs)
surgical choices:
In refractory situations, catheter ablation.
Question 4: Kinds of Anaemia, Their Causes, Their Symptoms, Their Treatment
One is iron deficiency anaemia.
Blood loss, poor diet, or malabsorption are the causes.
Fatigue, pallor, brittle nails, pica are symptoms.
Therapy: Ferrous sulphate oral iron pills.
Dietary adjustments including meals high in iron (red meat, spinach).
2. Pernicious Anemia—Vitamin B12 Deficiency
Reasons could be malabsorption, vegan diet, or lack of intrinsic component.
Symptoms: glossitis, tiredness, neuropathy.
Treatment consists in oral supplements or vitamin B12 injections.
3. Folate Shortage Anaemic
Reasons: Pregnancy, drinking, bad nutrition.
Shortness of breath, irritation, and tiredness define the symptoms.
Treatment: supplemented folic acid.
4.hemolytic anaemia
Causes: infections, autoimmune diseases, or hereditary conditions including sickle cell anaemia.
Dark urine, jaundice, splenomegaly.
For autoimmune reasons, treatment consists in corticosteroids or immunosuppressants.
Blood transfusions for serious conditions.
5. Applastic Anaemia
Causes: Radiation, poisons, or autoimmune illnesses can all cause bone marrow failure.
Symptoms include easy bruising, tiredness, and repeated infections.
Therapy: Bone marrow transplant.
Immunosuppressive treatment.
