Diagnosis of obstructive HCM consistent with 2020 American Heart Association/American College of Cardiology (AHA/ACC) guidelines. ii. Obstructive HCM is defined clinically by the presence of increased LV wall thickness = 15 mm (or = 13 mm with positive family history of HCM) in a nondilated ventricular chamber that is not solely explained by abnormal loading conditions (eg, another cardiac or systemic disease) and peak LVOT gradient of = 30 mmHg at rest or with provocation.

3. Symptoms consistent with NYHA functional class II-IV.

4. = 18 years of age at the time of informed consent.

5. Receiving BBs, non-dihydropyridine calcium. channel blockers (non-DHP CCBs), disopyramide, and/or mavacamten (once available) as part of routine clinical care; or currently receiving no treatment due to intolerance or failure of prior treatment (eg, BBs, non-DHP CCBs, or disopyramide) for obstructive HCM.

Exclusion Criteria:

1. Known phenocopy disease (eg, Fabry disease, amyloidosis) or LV hypertrophy associated with hypertension.

2. Documentation of any fixed obstruction of the outflow tract such as aortic valve stenosis or replacement.

3. Prior treatment of obstructive HCM with invasive septal reduction (surgical myectomy or percutaneous alcohol septal ablation [ASA]) within 6 months prior to enrollment; participants with an unsuccessful myectomy or percutaneous ASA performed > 6 months prior to enrollment may be enrolled.

4. Naïve to treatment for obstructive HCM (ie, never treated with BBs, non-DHP CCBs, or disopyramide).

5. Receiving an investigational therapeutic agent for obstructive HCM (eg, myosin-inhibitors other than mavacamten) in an interventional clinical trial at participant enrollment.

6. Previously or currently enrolled in a long-term safety extension study of mavacamten (eg, EXPLORER-HCM [ClinicalTrials.gov, NCT03470545], MAVA-LTE [NCT03723655], PIONEER-OLE [NCT03496168], VALORHCM [NCT04349072], or MAVERICK [NCT03442764])

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Incidence rate of new or worsening heart failure due to systolic dysfunction among participants with symptomatic obstructive HCM during periods of exposure to mavacamten and other oHCM treatment	Systolic dysfunction defined as symptomatic Left Ventricular Ejection Fraction (LVEF) < 50%	Up to 5 Years
Secondary	Occurrence of arrhythmia	Incidence rates of participants with arrhythmia (new onset)	Up to 5 Years
Secondary	Occurrence of Major Adverse Cardiovascular Events (MACE)	A composite endpoint consisting of non-fatal acute Myocardial Infarction (MI), stroke, hospitalization due to Heart Failure (HF) and Cardiovascular (CV) mortality	Up to 5 Years
Secondary	Occurrence of non-fatal acute Myocardial Infarction (MI)		Up to 5 Years
Secondary	Occurrence of Stroke		Up to 5 Years
Secondary	Occurrence of hospitalization due to heart failure		Up to 5 Years
Secondary	Occurrence of cardiovascular mortality		Up to 5 Years
Secondary	Occurrence of all-cause mortality		Up to 5 Years
Secondary	Evaluation of functional responses: New York Heart Association (NYHA) function class	Percentage of Participants Whose NYHA Class Changes	Up to 5 Years
Secondary	Evaluation of functional responses: Left Ventricular Outflow Tract (LVOT) gradient	Mean Change From Baseline in LVOT Gradients At Rest and Provoked	Baseline, 5 Years
Secondary	Evaluation of functional responses: LVEF	Mean Change from Baseline in LVEF	Baseline, 5 Years
Secondary	Evaluation of patient reported outcome measure: Kansas City Cardiomyopathy Questionnaire 23 (KCCQ-23)	The KCCQ-23 is a disease-specific health status instrument composed of 23 items that quantifies the domains of physical limitations, symptoms, self-efficacy, social limitation and quality of life from heart failure. Scores range from 0-100, in which higher scores reflect better health status.	Baseline, 5 Years
Secondary	Evaluation of patient reported outcome measure: EuroQol Five Dimensions Questionnaire (5-level) (EQ-5D-5L): Health Utility Index	The EQ-5D-5L is a 2-part instrument for use as a measure of health outcome, designed for self-completion by respondents. It consists of EQ-5D-5L health utility index and EQ Visual Analog Scale (VAS). EQ-5D-5L health utility index is comprised of 5 dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each has 5 levels of perceived problems (1-no problem, 2-slight problems, 3-moderate problems, 4-severe problems, 5-extreme problems). Participants select an answer for each of the 5 dimensions that best matches his/her health "today". Responses are used to generate a weighted summary index, which ranges from 0 to 1.00. A higher score indicates better health and positive changes from baseline indicate improvement of health.	Baseline, 5 Years
Secondary	Evaluation of patient reported outcome measure: EQ-5D-5L: VAS	The EQ-5D-5L is a 2-part instrument for use as a measure of health outcome, designed for self-completion by respondents. It consists of EQ-5D-5L descriptive system and VAS.; The VAS self-rating records the participant's own assessment of his or her overall health status at the time of completion, on a vertical line VAS with scale of 0 (the worst health you can imagine) to 100 (the best health you can imagine). A higher score indicates better health and positive changes from baseline indicate improvement of health status.	Baseline, 5 Years
Secondary	Evaluation of biomarkers of response: NT-proBNP	Change From Baseline in Serum concentration of NT-proBNP	Baseline, 5 Years
Secondary	Evaluation of biomarkers of response: Cardiac troponin	Change From Baseline in Serum Concentration of Cardiac Troponins	Baseline, 5 Years
