Hypertension atrial fibrillation

Valvular heart disease with thrombogenic complications (e.g., pulmonary hypertension, atrial fibrillation, history of endocarditis)... 

The co-prescription of sotalol 80 mg bd with terfena-dine 60 mg bd (both drugs that can prolong the QT interval) in a 71-year-old lady with hypertension, atrial fibrillation, and nasal congestion was complicated by recurrent torsade de pointes, causing dizzy spells and confusion after 8 days (412). She was treated with temporary pacing, but her symptoms resolved 72 hours after drug withdrawal.

The major modifiable risk factors include hypertension and cardiac disease (especially atrial fibrillation). 

Pindolol, like nadolol, is a nonselective 8-adrenoblocker. It possesses antianginal, antihypotensive, and antiarrythmic action. It is used for arterial hypertension, angina stress (preventing attacks), supraventricular tachycardia, tachsystohc form of atrial fibrillation, and superventricular extrasystole. Synonyms of this drug are carvisken, visken, and others. 

Verapamil is used for preventing angina pectoris attacks, arterial hypertension, and treating and preventing supraventricular arrhythmia (paroxysmal supraventricular tachycardia, atrial fibrillation, atrial flutter, extrasystole). Synonyms of this drug are isoptin, calan, fmoptin, falicard, manidone, and many others.

Atrial fibrillation is commonly associated with heart failure, and the prevalence of atrial fibrillation is related to the severity of heart failure, with less than 5% affected with very mild heart failure to nearly 50% affected with advanced heart failure [66]. Heart failure and atrial fibrillation are both common cardiovascular disorders and share the same demographic risk factors, including age, history of hypertension, prior myocardial infarction, and valvular heart disease [67, 68]. Further, the incidence of heart failure increases dramatically after the diagnosis of atrial fibrillation [69]. Progression of LV dysfunction can clearly be associated with rapid ventricular rates [70-76]. Conversely, conversion to normal sinus rhythm or control of ventricular response in atrial fibrillation can improve LV function [71-74, 77]. Accordingly, rate control becomes very important in patients with heart failure and dilated cardiomyopathy, and likely even more so when ischemia from rapid rates complicate the patient s course.

Hypertension, hypotension, arrhythmias such as sinus bradycardia, atrial fibrillation, varying degrees of AV block, ventricular ectopy including nonsustained tachycardia, and ECG abnormalities have been observed,... 

Anemia, hypertension, tachycardia, atrial fibrillation, and somnolence occur more frequently with 90-mg doses. 

Headache, rash, temporary decrease in diastolic BP with mild reflex tachycardia, short periods of atrial fibrillation (in hyperthyroid patients), marked drop in BP (in hypertensive patients)... 

Dobutamine improves atrioventricular conduction and may precipitate atrial fibrillation in susceptible patients. Hypertension and tachycardia may also occur in some patients. 

During the acute phase of thyrotoxicosis, B-adrenoceptor blocking agents without intrinsic sympathomimetic activity are extremely helpful. Propranolol, 20-40 mg orally every 6 hours, will control tachycardia, hypertension, and atrial fibrillation. Propranolol is gradually withdrawn as serum thyroxine levels return to normal. Diltiazem, 90-120 mg three or four times daily, can be used to control tachycardia in patients in whom blockers are contraindicated, eg, those with asthma. Other calcium channel blockers may not be as effective as diltiazem. Adequate nutrition and vitamin supplements are essential. Barbiturates accelerate T4 breakdown (by hepatic enzyme induction) and may be helpful both as sedatives and to lower T4...

A 78-year-old man became short of breath. He had been taking rosiglitazone 8 mg/day for 6 months. He had renal insufficiency, atrial fibrillation, hypertension, and congestive heart failure, with pitting edema and bilateral pleural effusions. He was refractory to intravenous furosemide and metolazone. Withdrawal of rosiglitazone and administration of bumetanide gave a net fluid output of 9.5 litres and the edema resolved. 

Of 86 cirrhotic patients treated with terlipressin 10 developed a tachycardia, four developed atrial fibrillation, and one developed ventricular tachycardia. Four patients in the same study developed hypertension (11). In another study, tachycardia occurred in 23% of patients randomized to pitressin for acute variceal bleeding and 8% developed transient hypertension (12). 

Clinical effects A large number of randomized, doubleblind, placebo-controlled trials have shown that the longterm use of (3 blockers improves the clinical status in patients with HF (22-32) (Table 2) and the ACC/AHA guidelines (II) recommend that (3 blockers should be routinely prescribed to all patients with asymptomatic LV dysfunction or stable HF caused by LV systolic dysfunction (unless they have a contraindication or have been shown to be intolerant to treatment with these drugs). (3 blockers should also be used in patients with HF and preserved LV systolic function, particularly when those patients have hypertension, coronary artery disease (CAD) and/or atrial fibrillation. 

Mr CD, a 75-year-old man, 1.7 m tall, is admitted to hospital very short of breath. He used to work in the docks as a clerk and has smoked 40 cigarettes daily for 30 years and stopped 2 years ago. His previous medical history includes COPD, recurrent infective exacerbations since 1991, no LTOT type 2 diabetes mellitus on insulin 14 IU b.d. for 20 years, retinopathy ischaemic heart disease - coronary artery bypass graft (twice), hypertension myocardial infarction 1986 atrial fibrillation high cholesterol. 

A 76-year-old woman, who had a history of hypertension, valvular heart disease (mitral regurgitation) with chronic atrial fibrillation, chronic obstructive airways disease, diverticular disease of the sigmoid colon, and generalized anxiety disorder, developed severe hypotension with a tachycardia after taking alprazolam for 7 days. She also had severe weakness, depressed mood, and impaired gait and balance, without clinical features of neuromuscular disease. 

Some of the association between atrial fibrillation and stroke must be coincidental because atrial fibrillation can be caused by coronary and hypertensive heart disease, both of which may be associated with atheromatous disease or primary intracerebral hemorrhage. Although anticoagulation markedly reduces the risk of first or recurrent stroke, this is not necessarily evidence for causality because this treatment may be working in other ways, such as by inhibiting artery-to-artery embolism, although trials of warfarin in secondary prevention of stroke in sinus rhythm have shown no benefit over aspirin (Ch. 24). 

Thorough cardiac examination should look for possible cardiac source of embolism, including atrial fibrillation, mitral stenosis and prosthetic heart valves. Left ventricular hypertrophy suggests hypertension or aortic stenosis, and a displaced apex from a dilated left ventricle indicates underlying cardiac or valvular pathology.
