==Overview==
==[[Alcoholic cardiomyopathy overview|Overview]]==
'''Alcoholic cardiomyopathy''' is a disease in which the excessive use of [[alcohol]] use damages the [[heart muscle]] causing [[heart failure]]. It is characterized by constellation of findings which includes a history of excessive alcohol intake, physical signs of [[alcohol]] abuse, [[heart failure]], and supportive findings consistent with [[dilated cardiomyopathy]].


==Pathophysiology==
==[[Alcoholic cardiomyopathy historical perspective|Historical Perspective]]==
Alcoholic cardiomyopathy is a type of [[dilated cardiomyopathy]]. Excessive use of [[alcohol]] has a direct toxic effect on the [[heart muscle]] cells. The heart muscle becomes weakened, subsequently dilates, and cannot pump [[blood]] efficiently. The lack of [[blood flow]] affects all parts of the body, resulting in damage to multiple tissues and organ systems. Alcohol may also simultaneously be causing direct damage to the [[liver]].


==Epidemiology and Demographics==
==[[Alcoholic cardiomyopathy pathophysiology|Pathophysiology]]==
Alcoholic cardiomyopathy is more prevalent in middle aged males between the ages of 35-50. However, females may be more sensitive to cardiotoxic effects of alcohol, and may develop alcoholic cardiomyopathy with lesser amounts of alcohol use, than males.


==Diagnosis==
==[[Alcoholic cardiomyopathy differential diagnosis|Differentiating Alcoholic cardiomyopathy from other Diseases]]==
===History and Symptoms===
The [[alcohol]] history, with attention to daily, maximal, and lifetime intake and the duration of [[alcohol]] consumption as well as the nutritional status of the patient should be inquired about.


Symptoms presented by the occurrence of alcoholic cardiomyopathy are the result of the [[heart failure]] and usually occur after the disease has progressed to an advanced stage. Therefore the symptoms have a lot in common with other forms of [[cardiomyopathy]].
==[[Alcoholic cardiomyopathy epidemiology and demographics|Epidemiology and Demographics]]==
*[[Anasarca]] or [[overall swelling]]
*[[Anorexia]]
*[[Cachexia]]
*[[Cough]] containing mucus, or pink frothy material
*[[Decreased alertness]] or [[decreased concentration]]
*[[Dyspnea]] or [[shortness of breath with activity]]
*[[Faintness]]
*[[Fatigue]]
*[[Irregular pulse]] or [[rapid pulse]]
*[[Nocturia]] or a [[need to urinate at night]]
*[[Oliguria]] or [[decreased urine output]]
*[[Orthopnea]] or [[breathing difficulty while lying down]]
*[[Paroxysmal nocturnal dyspnea]]
*[[Palpitations]]
*[[Pedal edema]], [[ankle swelling]], [[feet swelling]], and [[leg swelling]]
*[[Weakness]]
===Physical Examination===
*Enlargment of the [[heart]] with a laterally displaced and diffused point of maximal impulse.
*Abnormal [[heart sound]]s, namely third [[S3]] and fourth [[S4]] sounds may be heard.
*Apical [[murmur]] of [[mitral regurgitation]] and the lower parasternal murmur of [[tricuspid regurgitation]] may be present secondary to papillary muscle displacement and dysfunction.
* [[Rales]] may be heard on lung exam due to pulmonary congestion.
*[[Jugular venous distention]], peripheral [[edema]], and [[hepatomegaly]] may be present secondary to elevated right heart pressures and right ventricular dysfunction.
*Cold extremities with decreased [[pulse]]s.
* Other sequelae of [[alcoholic liver disease]] may also be noted on physical examination.


===Electrocardiogram===
==[[Alcoholic cardiomyopathy natural history, complications and prognosis|Natural History, Complications and Prognosis]]==
*Reduced [[QRS]] voltage may be present.
*[[T wave alternans]] may be present.


===Chest X Ray===
==Diagnosis==
*[[Chest x ray]]s usually show evidence of [[cardiomegaly]] or [[an enlarged heart]], [[pulmonary congestion]], and [[pleural effusion]]s.

===Echocardiography===
*[[Echocardiography]] is the most useful initial diagnostic test in the evaluation of patients with [[heart failure]]. Because of its noninvasive nature and the ease of the test, it is the test of choice in the initial and follow-up evaluation of most forms of [[cardiomyopathy]]. It provides information not only on overall heart size and function, but also on valvular structure and function, wall motion and thickness, and pericardial disease.
 
===Other Diagnostic Studies===
*[[Cardiac catheterization]] or [[angiogram]] to rule out coronary artery blockages.


==Treatment==
==Treatment==
Treatment for alcoholic cardiomyopathy involves lifestyle changes, including complete abstinence from [[alcohol]] use, a low sodium diet, and fluid restriction, as well as medications.  If the [[heart failure]] is severe, the effectiveness of treatment will be limited.

Medications may include, [[ACE inhibitors]] and [[beta blockers]] which are commonly used for other forms of [[cardiomyopathy]] to reduce the strain on the [[heart]]. [[Diuretic]]s can also be used to help remove the excess fluid from the body. Persons with [[congestive heart failure]] may be considered for surgical insertion of an [[ICD]] or a [[pacemaker]] which can improve the heart function. In cases where the [[heart failure]] is irreversible and worsening, a [[heart transplant]] may be considered.


Treatment will possibly prevent the [[heart]] from further deterioration, and the [[cardiomyopathy]] is largely reversible if complete abstinence from [[alcohol]] is maintained.
