Presentation
In family A, a novel R349L mutation was present in the mother and her identical twin daughters. They required cardiac transplantation at 36, 18, and 20 years of age. [ncbi.nlm.nih.gov]
At diagnosis he presented grade 1 AVB and left bundle-branch block with a CPK of 192 U/l (normal up to 195 U/l). A sister (II: 2) presented DCM and LBBB. Two of her offspring (III: 1 and III: 3) had LVE in the electrocardiogram. [revespcardiol.org]

Palpitations
He gave history of palpitation off and on at rest, associated with chest pain and breathlessness in the last 2 years. There was no definite aggravating or relieving factor. [ijpmonline.org]

The most common presentation was shortness of breath (58%), followed by palpitation (17%). Diastolic dysfunction was noted in all patients, whereas systolic dysfunction was subclinical in four, mild to moderate in four, and severe in three patients. [cags.org.ae]
The symptoms include dyspnea, syncope, collapse, palpitations, and chest pain. They can be readily provoked by exercise. [uniprot.org]

Workup
The detailed diagnostic workup and possible red flags are presented in Table 3. [intechopen.com]
Workup is focused on identifying any possible reversible causes. Recommended laboratory testing includes thyroid function tests, HIV serology, electrolytes, and iron studies (to rule out hemochromatosis). [statpearls.com]
The diagnosis of a particular seizure type, and of a specific type of epilepsy (epilepsy syndrome), directs the diagnostic workup of these patients and their initial therapy. [ncbi.nlm.nih.gov]

First-Degree Atrioventricular Block
A sister of one of the first-degree relatives with high LVE and CPK cited had a CPK of 188 IU associated with first-degree atrioventricular block. [revespcardiol.org]
Rhythm

Premature Atrial Contractions
Stage I occurs in the second and third decades and is characterized by absence of symptoms, normal heart size, sinus bradycardia, and premature atrial contractions. Stage II is marked by first-degree AV block in the third and fourth decades. [gwumc.edu]

Prognosis
Overall, the prognosis of patients with dilated cardiomyopathy is guarded. [statpearls.com]
Prognosis Status of Prognosis Patients with DCM generally have an ominous prognosis. DCM is a frequent cause of heart failure and the primary indication for heart implantation [18]. [oatext.com]
Prognosis MSL is basically a benign condition but in some cases, there may be serious physical, cosmetic and psychological repercussions. Associated disorders may affect the prognosis. [orpha.net]
The prognosis of DCM patients is variable and depends on multiple risk factors. [intechopen.com]
Identification of these areas and restoration of their perfusion through revascularization might improve the ejection fraction and long-term prognosis. [clevelandclinicmeded.com]

The idiopathic category should continue to diminish as more information explaining pathophysiologic mechanisms, specifically genetic-environmental interactions, becomes available. Toxins are a significant cause. [emedicine.medscape.com]
Prevention
Key benefits include: Clarify diagnosis and risk for sudden cardiac arrest Target medical management and prevention of cardiac arrest and other complications Adjust management in those with DCM due to a specific cardiac genotype, or underlying conditions [ambrygen.com]
Both salt and water restrictions are necessary to prevent symptoms. Patients should remain physically active or enroll in a cardiac rehab program. [statpearls.com]
However, all these approaches need further research. 2.9 Prevention of sudden cardiac death The most effective therapy of malignant VTs and thus prevention of SCD in DCM patients is the implantation of an ICD. [intechopen.com]
The primary indication of ICD therapy is the prevention of sudden cardiac death in idiopathic DCM and selected secondary DCM. [oatext.com]
Early diagnosis is indicated for 2 reasons: treatment of significant arrhythmias may prevent sudden unexpected death, and genetic counseling can be provided. [gwumc.edu]
