Primary care

Ventricular tachyarrhythmias remain a major cause of sudden cardiac arrest (SCA) that leads to sudden cardiac death (SCD). Primary prevention strategies to prevent SCD include promoting a healthy lifestyle, following United States Preventive Service Task Force recommendations related to cardiovascular disease, and controlling comorbid conditions. For a patient experiencing SCA, early cardiopulmonary resuscitation and defibrillation should be performed. Implantable cardioverter defibrillators are more effective at secondary prevention compared with drug therapy but medications such as amiodarone, beta-blockers, and sotalol may be helpful adjuncts to reduce the risk of SCD or improve a patient's symptoms (eg, palpitations and inappropriate defibrillator shocks).

Lifestyle medicine is a cornerstone of cardiovascular disease prevention and early disease intervention. A leading cause of death in developed countries, modifiable risk factors of cardiovascular disease like diet, exercise, substance use, and sleep hygiene have significant impacts on population morbidity and mortality. One should address these amendable risks in all patients, independently, and stress the importance of intervention adherence while avoiding the sacrifice of patient trust. One must also understand a patient's psychological well-being can be compromised by organic chronic disease states, and poor psychological well-being can have a negative impact on patient compliance and overall health.

Heart failure is defined by stages that are based on symptoms from at risk individuals to those with refractory symptoms. Along this continuum of care, we initiate optimal treatment that is then based on an individual's ejection fraction. Therapy is designed to reduce the progression of heart failure while reducing heart failure complications, deaths and hospitalizations.
